What You Need To Know...

MAFS.912.A-APR.4.6 – Rewrite and recognize rational expressions in different forms.

1. The benchmark will be assessed using Drag and Drop Response, Equation Response, Graphic Response, Multiple Choice Response, Multi-select Response or Open Response.
2. Items may require students to know and apply the Remainder Theorem for determining factors and/or zeroes.  For a polynomial p(x) and a number a, the remainder on division by x – a is p(a), so p(a) = 0 if and only if (x – a) is a factor of p(x).
3. Items may require students to rewrite expressions by inspection or by long division.

Example Two

Use the Fundamental Theorem of Algebra and Descartes' Rule of Signs to find the number of possible positive, negative, and complex zeros for the following function:

Example Three

Rewrite by Inspection
Rewrite Using Long Division
Rewrite with Factoring
