Khan Academy: Algebra Ii: Divide Polynomials by Linear Expressions

Rewrite rational expressions of the form a(x)/b(x), where a(x) is a polynomial and b(x) is a linear binomial, in the form q(x)+r(x)/b(x), where q(x) and r(x) are polynomials and the degree of r(x) is less than the degree of b(x). Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.
