You can then solve the equation that you got in the fourth step.

Check the results if you want to ensure that the answer had satisfied the requirements of problems.

An expression which is written as ax2+bx+c=0 is the quadratic solution but a should be different to zero. The equation is also called standard or general form. It is possible to solve the quadratic equation by using the formula or by factorization. The formula is to get the root for the quadratic equation, and it is as follows.

Now it is easy to solve the applied problems because of the wide variety of the applied problems. You cannot find any single technique to solve the equation in every case.

If you find problems with solving quadratic equations, then online tutor is the right way to go. The tutor offers the best way to deal with the math problems.  Many students have a problem in math while there is always an emphasis on getting good grades to get job placement. Math tests at the metric measurement are an example of the terrible anxiety, and many students will not have any choice but getting the help needed so that they may gain their confidence.   The tutor will develop the learning process and will develop a customized instructional program.

How to Solve Quadratic Equations within a minute without a Calculator?

A quadratic equation is the branch of algebra which is the important part of mathematics. It includes three important terms as variable, content, and coefficient. Before going to solve the equation without greatest common factor, you need to know some basics about the algebraic expression. The quadratic algebraic equation includes 2nd order degree on the variable. Hence, there are two values you can find for a variable. Consider an example as mx² + nx + p = 0

Here some of the common term as

Variables: Variables are the term whose value varies with constant and coefficient available in the mathematical expressions. Here ‘x’ is the variable in given equation.

Constant: Constant value is the numerical value or number available in the equation which cannot be changed. In the above equation, the ‘p’ is the constant value.

Coefficient: in the term of any algebraic equation, a coefficient is also the numerical value. In the given standard quadratic equation’ and ‘n’ are coefficients.

How to solve the quadratic equation without a calculator?

Consider examples to solve the quadratic equations without using the calculator and formulas.

x² + 5x + 6 = 0

x² – 5x + 6 = 0

x² – 5x – 6 = 0

x² + 5x – 6 = 0

There are four quadratic examples, and it can be solved without the formula method. It is easy when you have great skill in mathematical calculation.

For first equation to solve it- 

x² + 5x + 6 = 0

First, you have to choose the right factor. For this, you have selected the coefficient of x² and constant value. After getting factors, you need to make set where the sum of these is equal to the coefficient of ‘x.’ now divide both the factors by the coefficient of x² . And the most important (+, +) signs make (-,-) in the result.

For above equation, factors are 1 and 6, and 6 can be factored as 2 and 3. The multiplication of 2×3 is equal to 6 and the sum of 2+3 = 5. So we get 2 and 3 as a result.

For second equation

x² – 5x + 6 = 0

We have (-, +) signs on the quadratic equation. The factors are 2 and three as identified above in the expressions. So, the signs provide (+, +) signs on the result. Now the equation provides two values as (3, 2).

For third equation

x² – 5x – 6 = 0

There are (-, -) signs are available which provide (+,-) signs on the result. The factors are 2 and 3 for the above equations. Keep the thing in mind that the first sign is for big numerical value. Now the value of ‘x’ is (3, -2).

For fourth equation

x² + 5x – 6 = 0

In algebra problem there are (+,-) signs which provide (-, +) signs in the result. And the first sign is always for the big numerical value. Now the equation provides (-3, 2) values for ‘x.’ in this method, dividing fractions is a difficult task. Also, you can experience the decimal to fraction and fraction to a decimal operation to make the complex equation simple.

Instead of this short method, the formula can be used.

There are many ways in which you can bring out the correct answers fir the value of “x” in the quadratic equations. Knowing the best one will help you to complete algebra homework on time. Therefore here are the methods used to solve quadratic equations:

Completing the Square: This is usually a process including multiple steps. In this method, the main motive is to convert the quadratic in the form of (x+a)² = b

  • The condition here remains the same,e., and b are constants. This method is the best to give perfect insights of the working of algebra. Also, this method is known to bring the correct answers always which are the advantage of using it. However, the disadvantage with it is the complexity it may involve.
  • Factoring: the factors of any quadratic equations will be said to be (max + r)
    and (nx + t). However, you will be able to find the correct answers only when the solution is an integer. Non integer solutions will not be found with this method which constitutes to its disadvantage. This method can be performed really faster, and it is the advantage with it.

Quadratic Formula: the formula is stated as:  -b±√b²-4ac ⁄ 2a the quadratic formula is designed in a way that it reduces the complex steps that are involved in solving a quadratic. This makes it straightforward which is the advantage. However the technique can turn out to be rote constituting to be the disadvantages.

Thus you can make use of these methods to complete your algebra homework. Though these are a bit complex than linear equations, you can make use of the simplest and the best methods. These will help you to solve quadratic equations and get the correct solutions.

How to Simplify System of Equations

There is a linear and nonlinear system of equations. The latter being a set of simultaneous equations whereby the unknowns appear as variables of a polynomial of degree higher than one in the argument of a function which isn’t a polynomial of degree one. Nonlinear equations are not always easy to deal with. Quadratic equations are examples of nonlinear equations. In short, a system of equations is a set of equations that are dealt with all together at a go.

Since solving these equations isn’t always a walk in the park, some guys decided to come up with a desktop application that simplifies them. They are called softmath, and they are based in the US. They called that app “Algebrator”.

How does algebrator work?

First of all, it can be downloaded through the link that is provided on their webpage softmath.com. As of now, its cost is roughly ten bucks. But, that is bound to change in the next few hours. So if you feel like purchasing it after paying attention to what it does, I would advise you to do that sooner rather than later.

Now, let us dive deep into Algebrator. This solution tackles problems from many math textbooks. It tackles those that are in Trigonometry, Statistics, Pre-Algebra, and College Algebra. Imagine it can solve problems from the following topics; complex numbers, graphing, trigonometry, equations, and inequalities, logarithms, functions, math expressions to name but few. Is that not great? I bet it is.

The app allows the use of wizards interface or WYSIYWG interface (an acronym of What You See Is What You Get interface) to enter problems like “Find a perpendicular line that passes the (x, y) coordinates”.

With this app, you can ask for the explanation of something if you did not get how it arrived at that place. Just like how the teacher shows his or her steps while calculating something, this application will do the same too. That way, it makes sure that you have understood how it some things are done.

When you get the solution, you can export it in MathML format. If you do not mind, you can go ahead and share that solution with your friends or classmates or even everyone. The application has an export function which generates xhtml files which can be easily opened in web browsers like Google Chrome, Mozilla Firefox, Internet Explorer, Microsoft Edge, Safari, Opera and many more.

Who can install this application?

As of now, the app can be installed on Windows PCs or Mac OS laptops.

Do they provide customer support service?

Yes, they do. Softmath provides customer services every week day from 8 o’clock in the morning to 9 o’clock in the evening. They can also be reached through the phone call using the number that they have indicated in their webpage.

If you prefer having a one on one talk, you can get them at their office which is located along Blanco Road in the city of San Antonio in the State of Texas.

Know dividing polynomials with small example to understand better

dividing polynomials

Dividing polynomials is not an easy task as it seems. Sometimes the polynomials equations include higher degree that is why it is difficult to solve it. Basically, the polynomial equation is same as the algebraic or the quadratic equation. But the major difference between both is the algebraic equation does not contain degree on variables, but quadratic includes it. The polynomial equation usually contains same variables in the quadratic form. To better understand consider an example which is suitable-

3a + 2b = 18 algebraic equation

x²+2x+ 8=0 Polynomial equation

When you are dividing polynomials, and then feel some difficulties. Due to lack of knowledge of mathematics operation and the complexity of polynomial; makes it more difficult. The variables include different values that are why it is hard to solve. There is no direct method to solve polynomial equations.

When you are looking for understating the dividing the polynomial consider an example.

x³+7x²+7x-6

This is divided by

x+2

The dividing rule is same as we have performed in previous classes. But the variable in dividing polynomials makes complexity in solution.

Take the figure in this form as below

(x³+7x²+7x-6)÷(x+2)

 

To solve this polynomial determine the degree of both the equation. As shown in the first equation has 3 higher degrees and the second includes one.

In the first step of division, to need to divide first equation by     x²

We take x² because it can eliminate the (x³) from the equation. In a first step, we can eliminate the higher degree than we go to the lower degree.

After division we have,

(5x²+7x)÷(x+2)

Now you have to follow the second step in which, the elimination of second-degree performs. Divide the equation with ‘5x’ that can help you to eliminate the term 5x².

Now we have taken 5 with the variable it is done to eliminate both x² and 5 from the equation. After dividing the above equation, you will get,

(-3x-6)÷(x-2)

Now we have eliminated the first and second degree. Now you have to eliminate the variable which includes a single degree. For this purpose, we need to repeat the previous step with different numerical values. Divide the above equation by (x-2) with (-3)’s multiplication. This will help you to eliminate (-3x) from the equation.

After division, you have 0 remnants. So, keep the numbers which are multiplied by the divider. Above we used

x² , 5x and -3

We need to add these results to get the final answer.

Hence the solution of this equation is

x²+5x -3

Basically, it is not difficult to solve the equation, but it needs huge grip in a calculation, division, multiplication and much more. Also, it needs great basic knowledge of mathematics for dividing polynomial. In the current, the polynomial equation is taken to know the intelligence of people. That is why it is used in many competitive exams. It makes the brain exercise perfect and helps to master in a calculation. It is beneficial for us so, we need to practice more and more to understand the division polynomial. After regular practice, you can become a master in it.

All about Linear and Quadratic Polynomials

Polynomials are algebraic terms which are two or more in numbers. They are also known as expressions and consist of the variable, constants, and coefficient. Besides this, they are of two types i.e. linear and quadratic polynomials plus they can be high degree and low degree. For solving them, you should be used to factoring methods and basic of algebra. So, let’s start our lessons.

How to solve linear polynomial?

At first, you should know how a linear polynomial looks like? In it, you will see variable with exponents one for example 3x+2. Let’s look at the steps for solving it:

  • Sat first you have to set the polynomials in which you have to insert an equal sign in front of it like this 3x+2=0.
  • Many people suggest you isolate terms but why to do that when you can give the answer by just looking at the expression.
  • What you have to do is to separate like terms like shift 2 to the RHS and 3x to LHS. In other change their sides like this, 3x=0-2. Sort out like terms, and with this simple trick, you can obtain the answer quickly.
  • Now, 3x= -2 and now bring three under two as like this x=-2/3.

You should take care of the similar terms, sides, and sign. Guys keep in mind that signs changes when you change the sides of the expression or constants.

How to solve a quadratic equation?

In it, the polynomial is of second degree which means that variables have exponent 2.

Let’ solve.

Math
Math
  • First thing guys, always make sure that the polynomial must be in right order. In other words, higher degree expression should come first or their degree must be in order.
  • Now, guys find out the factors of 20 plus you should use these factors in a way that it will give (-8) and will also give 20 when multiplied together.
  • You have to multiply one with 20 as the coefficient of is one plus for finding factors, it is an important to step.
  • 2, 2 and 5 are its factors so you should simplify it in a way mentioned above. Let’s multiply 5 and 2 to get 10 and leave two alone. It is also known as a grouping of factors.
  • Now, write four expressions like this
    Math
    Math

    . Now, divided them from the middle and formed two groups. Do like this: x(x+10)-2(x+10)=0 . Here we have taken x and two as common terms.

  • Also, while splinting into expressions, make sure you write signs right. The two group of binomials are visible to you i.e. ( x+10) and (x-2).
  • Now, you have to solve it like linear polynomials and get an answer(x=-10,x=2). Again, while using zero in the polynomial, change sings

Algebra is a very easy topic, and polynomials are like basics for other topics like linear or quadratic equations. You can solve another example of polynomials by the steps describe above plus understand properly how to group factors in it?
