#-9#

Explanation:

Start with distributing the negative infront of the second set of parenthesis. And after that, you can pretty much drop the parenthesis, which is visually better (at least for me!):

#-3-5i+3-4i#

Combine like terms:

#-9i#

Considering it's using imaginary numbers, it's hard to do anything, so the most you can do is simplify.
