  1. Rational Expressions Adding Subtracting

  2. Finding the Least Common Denominator (LCD) Step 1 Factor the denominators. Write any repeating factors in exponential form. Step 2 List different factors. If common factors, list the common factor with the highest exponent. Step 3 The LCD is the product from step 2.
