You can put this solution on YOUR website!
%28x%2B5y%29%5E2
is basically
%28x%2B5y%29%28x%2B5y%29
By using FOIL
First-
x%2Ax=>x%5E2
Outer-
x%2A5y=>5xy
Inner-
5y%2Ax=>5xy
Last-
5y%2A5y=>25y%5E2
Thus add all of the separate components together to get
x%5E2%2B5xy%2B5xy%2B25y%5E2
Simplify
x%5E2%2B10xy%2B25y%5E2
