In this lesson I will introduce you to quadratic equations. The topic of quadratic equations is really a study of polynomials where the highest power (degree) is 2. Quadratic equations are so important in algebra and more advance math so you want to work extra hard to master the concepts. As I was saying a quadratic equation is a type of polynomial. It goes without saying that you want to know about polynomials before studying quadratic equations. Depending on what course you are in you will learn how to solve quadratic equations, graph quadratic equations/inequalities and a host of other aspects of what makes quadratic equations so important in algebra.
