Add, subtract, and multiply polynomials.
- The benchmark will be assessed using MC(Multiple Choice) items.
- Items may require multiplication of two monomials, a monomial and a binomial, a monomial and a trinomial, or two binomials.
- 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
