K I have to put this ellipse into standard form. I get most of it. But I get confused in the ending part. So here is my work so far
16x^2 + 9y^2 -32x +72y + 16 = 0
I completed the square and then got to
==> 16(x-8)^2 + 9(y+4)^2 = -64

What do I do next? I know there is more. It needs to equal to 1. Thanks
