Today we learned how to add and subtract rational expressions with unlike denominators with Notes #38.
The key thing to remember is that you must first find a common denominator. Factoring the denominators helps you find the LCD, which will save you time! After that, just follow the same process as we learned before the Thanksgiving break.
Homework #60: TB pg 547 (#17-39 odd, #50)
Be sure to check your answers in the back of the book when finished!
