Introduction
This lesson will teach you how to solve quadratic equations using a variety of methods. Here are the sections within this lesson:

A quadratic equation is an equation that can be written in the form... ...such that the a-value is not equal to zero.

The term 'quad' from 'quadratic' relates to a square due to the x-squared term.

The sections below will explain how to solve quadratic equations using a variety of methods.

This method describes how to solve quadratic equations by factoring the quadratic polynomial into a product of two binomials. This lesson requires a prerequisite knowledge of factoring. esson: Solving Quadratic Equations by Factoring esson: Completing the Square
