11.2: Multiplying & Dividing Rational Expressions Goal: to multiply, divide and simplify rational expressions as well as complex fractions.

Simplified form of a rational expression - Means the numerator and denominator have NO common factors. If the numerator and/or are polynomials, factor them ALL THE WAY, then cancel common factors. ** Hint for simplifying: FACTOR EVERYTHING FIRST!! (told you factoring wasn’t going away anytime soon)

Examples: Simplify.

Examples: Simplify.

Examples: Simplify.

More Examples: Simplify. (Hint: Factor everything first!!)

Another Example:

One example using Division: Remember: We never divide fractions. We KCF.

THE LAST EXAMPLE!!! Remember: We never divide fractions. We KCF.
