%28-2-2i%29-%28-5-8i%29..first eliminate parentheses; here you just erase them -2-2i, and here -%28-5-8i%29 you have negative sign in front which means all inside parentheses is multiplied by -1:-1%2A%28-5%29-%281%29%2A%28-8i%29=5%2B8i


-2-2i%2B5%2B8i...group like terms together
%28-2%2B5%29%2B%288i-2i%29

3%2B6i....this is your answer
