the first one is a parabola and the second one is an ellipse

x^2 = 8 + 2y
36 - 9y^2 = 8 + 2y
9y^2 + 2y - 28 = 0

need to solve it using the quad formula

not really sure what the end result was supposed to be...but i got it down to:

x^2 = 8 - 2y
x = 2 - y

also keep in mind that i haven't had a formal math class in a couple years now...but thanks, i had fun (i'm a math nerd at heart)
