Assuming we are asked to simplify the given expression, here is my step-by-step explanation.
First, we can expand the parentheses by distributing, giving us
. Now, we combine like terms. This leaves us with
, which is our answer.
Assuming we are asked to set this quadratic equal to
and solve, we have:


Using the Zero Product Property, we get:
and
.
So, m=-4 and m=8 is our answer.
