Khan Academy: Divide Polynomials by Monomials (With Remainders)

Rewrite rational expressions of the form a(x)/b(x), where a(x) is a polynomial and b(x) is a monomial, 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.
