1. Complex/imaginary numbers?

Okay so im taking this online test and i have no idea what to do, i think i am right so far though but i don;'t know what to do next

z1=3+4i
z2=(-4-7i
z3=-6+3i

To solve:
z1*(z2+z3)

so far ive done the right side because im pretty sure you have to do that side first and im at...
3+4*[(-4-7i)+(6+3i)]
-10-4i^2
-10-4(-1)
-10+4
-6

so am i doing this right, if im not then can someone please help me out? lol, with work shown thanks a lot!=]

It is against MHF policy to ask for help on assignments that count for a final grade (i.e. tests, quizzes, etc.).

However, if you can post a similar problem, we can help you out.
