- HSA-APR.D.6Rewrite simple rational expressions in different forms; write <sup>a(x)</sup>/<sub>b(x)</sub> in the form q(x) + <sup>r(x)</sup>/<sub>b(x)</sub>, where a(x), b(x), q(x), and r(x) are polynomials with the degree of r(x) less than the degree of b(x), using inspection, long division, or, for the more complicated examples, a computer algebra system.
- HSA-APR.D.7(+) Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.

HSA-APR.D.6

Rewrite simple rational expressions in different forms; write ^{a(x)}/_{b(x)} in the form q(x) + ^{r(x)}/_{b(x)}, where a(x), b(x), q(x), and r(x) are polynomials with the degree of r(x) less than the degree of b(x), using inspection, long division, or, for the more complicated examples, a computer algebra system.

Speed Dating Rationally

12th Grade Math

Â» Unit:

Rational Functions and Equations

Big Idea:Efficiency and accuracy improves as students solve rational equations with their âdateâ in this interactive and self-checking speed dating activity.

Proving Polynomial Identities

Algebra II

Â» Unit:

Polynomial Theorems and Graphs

Big Idea:There are links between polynomials and geometry. Both branches of math use proof and a polynomial identity can be used to generate Pythagorean triples.

Review of Polynomial Roots and Complex Numbers

Algebra II

Â» Unit:

Polynomial Theorems and Graphs

Big Idea:Arithmetic with polynomials and complex numbers are performed in similar ways, but powers of i have a meaning distinct from powers of variables.

The Remainder Theorem

Algebra II

Â» Unit:

Polynomial Theorems and Graphs

Big Idea:Any polynomial p(x) can be written as a product of (x â a) and some quotient q(x), plus the remainder p(a).

Rationally Synthetic

Algebra II

Â» Unit:

Algebraic Arithmetic

Big Idea:Help your students connect the dots from long division to polynomial long division to synthetic division.

Quiz and Intro to Graphs of Polynomials

Algebra II

Â» Unit:

Polynomial Theorems and Graphs
