Benchmark MA.912.A.4.3 Factor polynomials expressions

This benchmark will be assessed using MC items.

Students will:Factor polynomials expressions which may include greatest common factor, difference of two squares, and trinomials

Content Limits:• All monomials in items will have, at most, two variables.• Coefficients must be integers.• In items requiring first factoring the GCF and then factoring the remaining

polynomials, the remaining polynomials must have a maximum degree of two. • In items that require simplifying algebraic ratios, the following factoring methods may

be used: GCF, difference of two squares, and/or trinomials.

Response Attributes:• Items that include rational expressions should state restrictions to the

domain or note that the value of the denominator is not equal to zero.• Distractors of rational expression items will not include expressions that are

equivalent to the correct answer.
