Question

Convert the equation to the standard form for a parabola by completing the square on x or y as appropriate. y2 + 2y - 2x - 3 = 0

A. (y + 1)2 = 2(x + 2) B. (y - 1)2 = -2(x + 2) C. (y + 1)2 = 2(x - 2) D. (y - 1)2 = 2(x + 2)

Answer 1

y^2+2 Y-2 X-3=0
Y^2+2 Y+1=2 X+3+1
(Y+1)^2=2 X+4=2(x+2)
Which is of the formY^2=4 a X
Which is a right formula.

Answer 2

Oooooh, got it. I feel stupid, I was getting a three at the end for some dumb reason. Thanks!
