You can't solve this, you have no equal sign, you can only simplify it.

Assuming the problem is:
- -
we want to change the signs in the third denominator so we can factor the difference of squares to:
- -
that changes the sign to:
- +
Factor
- +
you can see we can put this over a single denominator
=
combine like terms, then factor
=
Cancel the (m+n), leaving us with
