If my memory is correct, general form is just Ax2 + By2 + Cx + Dy + E = 0. In this case, A and B are 1. Just expand what you have to write your equation in general form.

okay, but
Ax2 + By2 + Cx + Dy + E = 0
where do i get E...
cause 12 is on the other side of the =

Then subtract 12 from both sides of the equation.
