-26-15i is the right answer. First you had to multiply by the parenthesis and you can also apply complex arithmetic rule. And it gave us, [tex](2*1-(-7)(-4))+(2(-4)+(-7)*1)i[/tex], and it gave us the answer is =-26-15i is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
