What is the standard form of the equation,
x%5E2-6x-7y=12.......complete square
%28x%5E2-6x%29-7y=12
%28x%5E2-6x%2Bb%5E2%29-b%5E2-7y=12.....b=6%2F2=3
%28x%5E2-6x%2B3%5E2%29-3%5E2-7y=12
%28x-3%29%5E2-9-7y=12
%28x-3%29%5E2=7y%2B12%2B9
%28x-3%29%5E2=7y%2B21
%28x-3%29%5E2=7%28y%2B3%29

The correct answer is:
A) %28x-3%29%5E2=7%28y%2B3%29
