## How to Solve Quadratic Equation GMAT Questions On The GMAT Test

When taking the GMAT test, you will most likely run into a math GMAT question that involves using the Quadratic Equation.

One type of even exponent question on the GMAT test is called the quadratic equation. An example of this equation is: x^2 + 6X + 5.

Quadratic equations are equations with 3 characteristics:

1. There is one unknown

2. There is a variable term raised to a second power

3. There is a variable term raised to the first power.

In order to solve a quadratic equation GMAT question, follow the steps below:

1. Move all of the terms to the left side of the equation, combine them, and then put them into the form:

ax + bx + c

The right side should now be equal to 0.

2. Factor the equation in the GMAT question. The trick to factoring is to find two integers whose product equals C and whose sum equals B.

3. Write the equation as (X+?)(X+?)

4. The left side is now a product of two equations. Since their product equals 0, one or both of the factors must be equal to zero. You can now solve for the solution.

Make sure to note: If you have a quadratic equation equal to 0, and then you factor an X out of the expression, then x=0 is a solution to the equation in the GMAT question.

An example of this is the GMAT question:

X^2+6X+5

Factor the equation: (X+5)(X+1)

Make both (X+5) and (X+1) equal to 0.

The answers are therefore -5 and -1.

We sincerely hope this was of help to you in studying for your GMAT questions.
