Chapter 11

POLYNOMIALS

Though a polynomial is no more than a sum of a ﬁnite number of terms,

each term usually the product of a real number and a variable raised to

some integer, the importance of polynomials cannot be overstated. This

chapter presents the most basic polynomial skills: classifying polynomials

and calculating polynomial sums, differences, products, and quotients.

Polynomials are like chains. Small clumps of numbers and variables

multiplied together called terms are strung together with addition

and subtraction signs. You’ve been dealing with polynomials for a while

now, even though you may not have known it. For instance, 2x + 1 is a

polynomial made up of two terms, 2x and 1. This chapter teaches you

how to describe polynomials and how to add them, subtract them,

multiply them, and divide them.

There are polynomials out

there that have an innite number

of terms, but you don’t deal with

those in algebra.
