Question #004e6

Answer:

#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.
