Chapter Eight

Section 8.1: You will investigate polynomial functions and learn how to sketch graphs of them without using a graphing calculator. You will also learn how to find polynomial equations from their graphs.

Section 8.2: Here you will solve equations you could not solve earlier by expanding the set of number you use. You will be introduced to a number system called complex numbers. You will learn what imaginary and complex numbers are, their properties and how they are used to represent solutions when graphs do not intersect.

Section 8.3: In this section, you will learn how to divide polynomials by applying your knowledge of area models and factoring. You will solve equations using polynomial division to factor polynomials.
