Find the vertex, focus, and the directrix of the parabola.
I get tripped up sometimes, but I know how to find all of the stuff with an equation like this :
(x+1)^2 +8(y+3) = 0
But how do I find it with equations like this
Can you complete the square with only two terms?

y2+ x= 0 is x= c.

since h and k are 0 then the vertex = (0,0)
How do I find the focus and the directrix though?
Focus maybe = 4p = -6 P= -3/2 so the focus (0,-3/2) ?????
