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 One ## 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
