# Lesson 2I Rule!Solidify Understanding

Rewrite each expression as the product of two binomials.

Each expression involves two multiplication problems separated by a or sign. Each multiplication problem contains a matching binomial factor that can be factored out so that the expression becomes a product of two binomials.

Example:

• Factor out and write the numbers that remain .

• Rewrite as .

## Set

In each set of three functions, one will be linear, one will be exponential, and one will be a quadratic function. Explain the nature of change for the function and find an explicit and recursive equation for each.
