This topic is in the 'Quadratic Equations and Functions' section. Quadratic equations are special cases of polynomials, because they have at most squared variables, whereas polynomials in general can have variables raised to any integer power. In this section we have tutorials focused on working with quadratic equations and showing tricks for factoring and solving quadratic equations. These equations are important because they come up a lot when we study things like moving soccer balls or other falling objects, and so it's a good idea to learn how to solve these equation!
