sqrt%28a%2B2%29%22=%22a%2B2

Square both sides:

a%2B2%22=%22%28a%2B2%29%5E2

a%2B2-%28a%2B2%29%5E2%22=%220

Put parenthese around a%2B2 and put a 1 coefficient before it:

1%28a%2B2%29-%28a%2B2%29%5E2%22=%220

Factor %28a%2B2%29 out on the left side:

%28a%2B2%29%22%5B%221-%28a%2B2%29%22%5D%22%22=%220

%28a%2B2%29%22%5B%221-a-2%22%5D%22%22=%220

%28a%2B2%29%28-1-a%29%22=%220
