Question

Simplify (-4 + 5i) + 2(1 + 3i). Enter your answer in the form a + bi.

Answer 1

-2 + 11i is your answer.

Answer 2

Answer: -2+11i

First distribute the 2 to rewrite the problem as (-4+5i) + (2+6i)

Now do -4 + 2 to get -2

And 5i + 6i = 11i

Now form the answer in a+bi

With -2 being a and 11i being bi

thus being -2+11i
