%28-1%2Bsqrt%283%29i%29%28-1%2Bsqrt%283%29i%29
We use the FOIL method,
First : %28-1%29%28-1%29=1+
Outer : %28-1%29%28sqrt%283%29i%29%29=-sqrt%283%29i
Inner : %28sqrt%283%29i%29%28-1%29%29=-sqrt%283%29i
Last : %28sqrt%283%29i%29%28sqrt%283%29i%29=3%2A-1=-3
Now sum all of the terms,
%28-1%2Bsqrt%283%29i%29%28-1%2Bsqrt%283%29i%29=1-sqrt%283%29i-sqrt%283%29i-3
%28-1%2Bsqrt%283%29i%29%28-1%2Bsqrt%283%29i%29=-2-2sqrt%283%29i
