  1. 9.2 Adding and Subtracting Rational Expressions Least Common Denominator of a polynomial

  2. Adding fractions What do you need to add or subtract fractions? A common denominator Of 5 and 3, it is 5 times 3 = 15 (Since both are prime numbers) We multiply. Since both numbers divide into 15, it is the Least Common Multiply

  3. What is the L.C.M. Given the terms To find the LCM of the numbers, find there factor multiplication.

  4. What is the L.C.M. The LCM is the highest number of each factor listed from each number.
