Work Step by Step
Step 1. Find $x$ values which need to be excluded from the domain of the two expressions (be sure to include the numerator of the dividend which becomes a denominator in the calculation).
Step 2. Factor the numerator and the denominator of each expression completely.
Step 3. Invert the dividend and multiply.
Step 4. Cancel all common factors in the numerator and the denominator and multiply the remaining factors in the numerator and denominator separately to get the answer.
