You can put this solution on YOUR website!
Note you had an i after the 10 as well, I believe that was a typo?
%28-10+%2B14i%29%2F%28-1%2B+i%29

%28-10+%2B14i%29%28-1-i%29%2F%28-1%2B+i%29%28-1-i%29

%2810-14i%2B10i%2B14%29%2F%281%2B1%29 Note: (A+B)(A-B) = A^2-B^2 and i^2 = -1

%2824-4i%29%2F2 = ANS 12-2i
