%284sqrt%28x%29+%2B+2%29%5E2
One way to simplify this is to use FOIL. A faster way would be to use the pattern:
%28a+%2B+b%29%5E2+=+a%5E2+%2B+2ab+%2B+b%5E2
In your expression, "a" is 4sqrt%28x%29 and "b" is 2. So by the pattern we get:
%284sqrt%28x%29%29%5E2+%2B+2%284sqrt%28x%29%29%282%29+%2B+2%5E2
which simplifies as follows:
16x+%2B+8sqrt%28x%29+%2B+4
(If you use FOIL, you should end up with the same thing.)
