# Chapter 9: Polynomials and Factoring; More on Probability

Difficulty Level:

**At Grade**Created by: CK-12

This chapter will present a new type of function: the **polynomial.** Chances are, polynomials will be new to you. However, polynomials are used in many careers and real life situations - to model the population of a city over a century, to predict the price of gasoline, and to predict the volume of a solid. This chapter will also present basic **factoring** - breaking a polynomial into its linear factors. This will help you solve many quadratic equations found in Chapter 10.
