Question

Algebra 2//PLEASE HELP ME...

Answer 1

Two fellow students, Theo and Paula, have added two rational expressions. They ended up at different answers so they have asked you to check their work. Please explain to them any errors that you find.
Theo Paula

Wally knows that in order to add or subtract rational expressions, he has to find the least common denominator first. Unfortunately, he can not remember how to do that. Using complete sentences, explain to Wally how to find least common denominators. Make sure you clearly explain any important items to consider.


Wally is very thankful for your help, but he is still stuck. Describe to Wally how adding and subtracting rational expressions is similar to adding and subtracting simple fractions, and how they are different.
