Question

factor (m/4 + n/3)(3m/4 - 2n/3)

Is this the answer? if not, what did I do wrong? 3m^2/16 + mn/12 - 2n^2/9

Answer 1

First factor out the common denominator of 12²=144, which then gives automatically the factorization:

(3m+4n)(9m-8n)/144

Answer 2

It's already factored. If you wanted to expand it, your answer is correct.
