Re: college algebra..2 problems help?

Please start a new topic (thread) with new problem.

I need help on this: I am to perform the indicated operation. Reduce to lowest terms.

4        +        4
____          ____
a-b            b- a

What is the relationship between (a-b) and (b-a)?

How can you exploit that relation in the problem above?
