## CCSS.Math.Content.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.
