Solving Quadratic Equations  
 
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 avalue is not equal to zero. The term 'quad' from 'quadratic' relates to a square due to the xsquared 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.  
This method involves relationships regarding squared binomials. To read more about this method, use the lesson link that follows.
