# How to solve with the quadratic formula

First, the quadratic factored form looks like this: y = a (x – r) (x – s) y = a (x – 2) (x – 6) [r = 2 and s = 6 are the two solutions of the quadratic equation] Now we just need to find the value of a. To Use the formula to solve theQuadratic Equation: y = x 2 + 2 x + 1 . Just substitute a,b, and c into the general formula: a = 1 b = 2 c = 1. Below is a picture representing the graph of y = x² + 2x + 1 and its solution.

The math equation is: 3 + 4 = 7.

Example 1: Find the Solution for x 2 + − 8 x + 5 = 0, where a = 1, b = -8 and c = 5, using the Quadratic Formula. x = − b ± b 2 − 4 a c 2 a. x = − ( − 8) ± ( − 8) 2 − 4 ( 1) ( 5) 2 ( 1) x = 8 ± 64 − 20 2. x = 8 ± 44 2. The discriminant b 2 − 4 a c > 0 so
