You can put this solution on YOUR website!
If you can calculate the polynomial product
%283-5x%29%282%2B6x%29 , you can almost calculate

At that point, you have to remember the newly learned fact/definition that
i=sqrt%28-1%29<-->i%5E2=-1 to substitute %28-1%29 for i%5E2
%283-5i%29%282%2B6i%29=+6%2B8i-30i%5E2=6%2B8i-30%28-1%29=6%2B8i%2B30=highlight%2836%2B8i%29
