Hi,
conic Forms:
Ellipse is %28x-h%29%5E2%2Fa%5E2+%2B+%28y-k%29%5E2%2Fb%5E2+=+1+
Hyperbola opening Up and down is: %28y-k%29%5E2%2Fb%5E2+-+%28x-h%29%5E2%2Fa%5E2+=+1
Hyperbola opening right and left is: %28x-h%29%5E2%2Fa%5E2+-+%28y-k%29%5E2%2Fb%5E2+=+1
Parabola opening up(a>0) or down(a<0), y=a%28x-h%29%5E2+%2Bk
Parabola opening right(a>0) or left(a<0), x=a%28y-k%29%5E2+%2Bh
x^2-8x-4y=-12
(x-4)^2 - 4y = -12 + 16
(x-4)^2 = 4y +4
y+=+%281%2F4%29%28x-4%29%5E2+-+1 Parabola opening Up
