Simplify the expressions below.
Factor the numerator and denominator.
After factoring, look for a Giant One to remove.
Refer to part (a).
This is division with fractions. Here is a sample division problem with numbers.
Step 1: Rewrite as multiplication by taking the reciprocal of the divisor.
Step 2: Factor
and use the Commutative Property to rewrite the problem so
there are Giant Ones.
Step 3: Remove the Giant Ones.
Apply these steps to part (c).
