Question #004e6

Answer 1

`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.
