## Polly, Want Some Division?

#### Activity Overview

In this activity, students will use polynomial calculations to determine quotients and remainders when performing polynomial division using CAS commands. The Remainder Theorem is introduced and applied to identify roots or zeros and to determine function values. Graphs are incorporated to visually illustrate outcomes of polynomial division.

#### Key Steps

• Problem 1 involves a basic review of terminology associated with division. Next, a basic example is provided to introduce the polynomial tools available on the TI-Nspire CAS handheld. This example is first observed graphically to illustrate the result of the degree of the quotient being less than that of the dividend.
