Answer:

a-b

Step-by-step explanation:

Solving the first bracket, the signs of both the a and b in the bracket reverse and thus they get cancelled by those outside the bracket. which in turn leaves us with -(b-a) and thus reversing the signs we get a-b.

Note: if there is a (-) sign outside the bracket, signs of those inside the brackets reverse.
