What's a Complex Expression with Rational Expressions?

Finishing up his short series on rational expressions, Sal reviews the concept with another example. Those who have a hard time with rational expressions will appreciate the clarity with which Sal explains his process and methodology.

Given a monomial and a polynomial, rewrite the expression as a rational number. This is not as confusing as you might think. First is to make the monomial a rational number by giving it a denominator. Once that is done, numbers can be...
