Quadratic Formula is derived from Method of completing the square.To find roots of any quadratic equation by Quadratic Formula,we first need to find the Discriminant of quadratic equation.If Discriminant less than zero no real roots exist for given quadratic equation.If Discriminant is greater than zero, real roots exist.If Discriminant is zero then roots of quadratic equation are equal.

Standard form of quadratic equation

First combine all the like terms in the quadratic equation.

Secondly, degree of each term must drop from left to right starting from 2.

Steps to solve Word Problems:

Step 1:Read the problem carefully to know what is given and what to find out.

Step 2:Denote the unknown by a small letter like z, p etc.

Step 3:From the given condition, frame the quadratic equation Involving the unknown.

Step 4:Solve by factoring quadratic equations
