expand? FOIL just like you would if they were real numbers, remembering that i^2=-1 8-8i-32i+32i^2=8-40i-32=-24-40i
But dividing wouldnt it be less in fraction?
oh i didnt see the division sign
Then it would be... 1+4i/2 ???
\[\frac{-2+8i}{-4+4i}*\frac{-4-4i}{-4-4i}\]

multiply top and bottom by \[-4-4i\] because \[(a+bi)(a-bi)=a^2+b^2\] a real number
mhm
what .sam. said denominator will be \[4^2+4^2=32\] all the work is multiplying in the numerator
but the result would be 1+4i/2 ???
