Multiplying Rational Expressions

When multiplying rational expressions it is very straight forward. You simply multiply across.

Follow these simple steps:
1. Factor your fractions

2. Cancel out common factors in the pattern 3/1 +|- 1/2 +|- 2/ 3

3. Multiply the numerators then multiply the denominators

4. You will now have your answer, add the non-permissible values (non-permissible values = numbers that the denominator cannot equal because the denominator will then equal 0)
