You can put this solution on YOUR website!
Let's see if we can "unconflict" you!
Multiply:
%283sqrt%287%29-6sqrt%283%29%29%2A%284sqrt%287%29%2B8sqrt%283%29%29 Use the FOIL method.
Simplify. Keep your eye on the two middle terms!
...as you can see, they drop out, leaving you with...
12%287%29-48%283%29
84-144+=+-60
