Can someone assist help me with the following?
Simplify the expression:
The answer is -2-3i, but I do not understand why.
Think of the -sign outside of the parantheses as a -1. So, you need the distributive law and multiply -1 x 8 =
-8. Then -1 x 3i = -3i.
So you have 6 + (-8) + (-3i)
-2 - 3i
Oh, thank you! That makes lots of sense. :)
