# Ch 9: Quadratic Functions & Polynomials

Use these video lessons and quizzes to help you understand parabolas, monomials and polynomials. Learn to solve, factor and graph quadratic equations and find their x- and y-intercepts.

## Quadratic Functions & Polynomials - Chapter Summary

Use the lessons in this chapter to find out what, exactly, a parabola is. Learn how to manipulate the direction of these functions by writing quadratic equations in the standard, intercept and vertex forms, and discover methods for maintaining the correct order of operations when multiplying binomials and factoring quadratic expressions.

Once you've mastered the basics, learn the steps for factoring a trinomial into a square binomial. You can also practice using the quadratic formula and study techniques for solving quadratic equations that aren't in standard form. Additional lessons show you how to graph a quadratic equation to locate the x- and y-intercepts. There are also tips for finding the maxima and minima of a quadratic function, determining the end behavior of a polynomial and graphing monomials. A lesson on factoring quadratic functions to find zeros rounds out the chapter, which is designed to teach you the following main topics:

• Prabolas
• Graphing monomials and polynomials

Our video lessons put the expertise of experienced instructors at your disposal. Watch them model the steps for solving quadratic equations and use the corresponding lesson transcripts to peruse the examples and explanations provided. If you'd like to try your hand at solving some of these problems, there are also quizzes to help you assess your comprehension of each lesson's content.
