Question #004e6

2 Answers

10-5i

Explanation:

The first step would be to distribute the negative outside of the parenthesis into the -8 and 3i. When you distribute the negative you should get this expression

-2i+8-3i+2

Then it's just a matter of combining like terms. So you would combine the -2i and the -3i and the 8 and 2. Making the answer come out to be 10-5i.

The ten will go first because it is a real number. The -5i will go second as the imaginary unit i is not real.
