In Unit 2 we will work primarily with polynomial functions to add, subtract, and multiply. When it comes to dividing, however, a bit of pre-work is required and we will investigate the GCF, "double-bubble," and grouping methods of factoring before learning how to use long division to simplify rational expressions that cannot be factored.

We will use the remainder theorem to help understand the significance of the remainder of a quotient and will then learn to use synthetic division to speed up the process if our divisor is a linear binomial with a lead coefficient of 1.
