Homework Help: Pre-cal

Posted by Randy on Thursday, May 6, 2010 at 7:21pm.

Find the vertex of y^2 + 4y + 2x +10 = 0. Use completing the square to put the equation into standard form as your first step. Could you show me how to get the vertex? Thanks

y^2 + 4y + 4 - 4 + 2x + 10 = 0
(y+2)^2 + 6 = -2x
x = (-1/2)(y+2)^2 + 6
