Simplify the expression (5-5i-) (-6-3i)

A) - 1-8i

B) 11-2i

C) - 11+2i

D) 9i

So I'm pretty sure you forgot the subtraction symbol between the parenthesis because I just had this question on my quick check.

The book says to add opposites when subtracting binomials so the equation will be

5-5i+6+3i

11-2i is your answer
