## What You Need To Know...

Add, subtract, and multiply polynomials.

1. The benchmark will be assessed using MC(Multiple Choice) items.
2. Items may require multiplication of two monomials, a monomial and a binomial, a monomial and a trinomial, or two binomials.
3. Items may be set in either real-world or mathematical contexts.

## Example One

Which expression is equivalent to the perimeter of the shaded portion of the rectangle? A.  2x + 10
B.  2x + 12
C.  4x + 14
D.  8x + 28

## Example Two

New photo imaging techniques on computers allow artists to distort an image from its original shape. Figure 1 is a square image.  Figure 2 is stretched 4 units wider and shrunk 4 units shorter than Figure 1. How many square units greater is the area of Figure 1 than the area of Figure 2?
