    Help getting parabola into standard form.

    Y^2 + x + 2y=5. I think it's x=-4p (y+1)^2 +5. Not sure though.

    Re: Help getting parabola into standard form.

    $y^2 + x + 2y = 5$

    $x = -y^2 - 2y + 5$

    $x = -(y^2 + 2y) + 5$

    $x = -(y^2+2y+1-1)+5$

    $x = -(y+1)^2+1+5$

    $x = -(y+1)^2 + 6$

    I'm going to barge in here with a quick note. Mathematics is "case sensitive" so the variable Y is not the same as the variable y.
