## Homework Statement

((a^3-b^3)/(a^2-2ab+b^2))/((2a^2+2ab+2b^2)/(9a^2-9b^2))

Not using complex number system.

Not concerned with domain.

Find the quotient and put it in simplest terms.

## Homework Equations

## The Attempt at a Solution

Too many to transcribe. Apparently I'm missing a legal operation somewhere. Wolfram|Alpha gives ((9)(a+b))/2, and I am able to reach equivalent answers, but not that simplest one.

Thank you for any help you can provide.
