(-8+4i)-(9-4i) Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! (-8+4i)-(9-4i)
Remove the brackets and combine like terms
Remember that if there is a minus in front of the bracket, you change the signs
inside brackets
:
-8 + 4i - 9 + 4i
-8 - 9 + 4i + 4i = -17 + 8i
