    If I have an equation in Standard form, how do I change it to Graphing (vertex) form?

    How do I make: y = ax^2 + bx + c, become y = a(x-h)^2 + k

    Thanks in advance.

    Thanks. Google wasn't being friendly for me, and I don't have my papers from two years ago.

    Don't know if u still need any help, cause those sites looked quite confusing to me, but in general...

    h and k are the coordinates of the vertex of the parabola and are equal to -

    h = -b/(2a)
    k =( c-b^2)/(4a)
