Adding Rational Expressions By Mack, Bryce, Mitchell, and Jenna
Example: • +
To add rational expressions with different denominators, you have to find the LCD-Least Common Denominator • Denominators have to be the same!
Example: • + = • Multiply Denominators: 9 4 = 36 so • + =
+ • Multiply denominators: 8g1 • Multiply 78g so: • + =
