Lesson 8-2: Adding and Subtracting Rational Expressions

2
Adding and Subtracting Rational Expressions Finding Least Common Multiples and Least Common Denominators! – Use prime factorization – Example: Find the LCM of 6 and 4 6 = 2·3 4 = 2 2 LCM= 2 2 ·3 = 12

3
Find the LCM 1. 18r 2 s 5, 24r 3 st 2, and 15s 3 t 2. a 2 – 6a + 9 and a 2 + a -12 3. 2k 3 – 5k 2 – 12k and k 3 – 8k 2 +16k
