Question 85808: Write the expression 8+4i/7+i in the form a+bi
I have tried multiply the equation by (7-i) but the answer doesn't work out. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Write the expression 8+4i/7+i in the form a+bi
----------------
[(8+4i)(7-i)] / [(7+i)(7-i)]
= [56+20i+4]/[50]
= [60+20i]/50
=(6/5) + (2/5)i
