Question

How do I solve this?

Answer 1

When you divide fractions, just multiply the first by the reciprocal of the second, like so:

\[\frac{ (w ^{2}-11w-12)(w ^{2} - 13w + 12) }{ (w ^{2} - 1)((w ^{2} + 13w + 12) }\]

Answer 2

Though I would recommend factoring those trinomials first

Answer 3

^yes, first step, before doing anything at all with these, is factor everything.
