(keep in mind, its circle math.. :/)
Write the equation (x+9)^{2}+(y5)^{2}=12 in general form.

If my memory is correct, general form is just Ax^{2} + By^{2} + 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 =
