4x%5E2%2B4y%5E2%2B12x-8y%2B25+=0

4%28x%5E2%2B3x%29%2B4%28y%5E2-2y%29=-25

4%28x%5E2%2B3x%2B%283%2F2%29%5E2%29%2B4%28y%5E2-2y%2B1%29=-25%2B4%283%2F2%29%5E2%2B4, this being Completing The Squares

4%28x%2B3%2F2%29%5E2%2B4%28y-1%29%5E2=-21%2B9

4%28x%2B3%2F2%29%5E2%2B4%28y-1%29%5E2=-12

%28x%2B3%2F2%29%5E2%2B%28y-1%29%5E2=-3
...Almost looks like a cirlce,...
A mistake must be somewhere.....
