Quadratic Equations The general quadratic equation is of the form . In order to solve a quadratic equation you must express the given equation in that form. The roots of a quadratic equation relate to the x-intercepts of the corresponding quadratic function. Solving Quadratic Equations by Factoring © 2017 E. Choi – MPM2D - All Rights Reserved

Solving Quadratic Equations Methods There are 3 methods used to solve a quadratic equation. By factoring By completing the square By Quadratic formula You are going to learn how to solve a quadratic equation by factoring in this section although you must be familiar with all of them in a long run.
