    find the coordinates of the vertex of the curve...

    State the coordinates of the verex of the curve

    y=x^2+8x+15

    I have completed the square:

    y=(x+4)^2-1

    I dont understand what the question is asking for or how i can find it though, please explain.
    Thanks

    Hi George321,

    You have just put the general quadratic into vertex form:

    y=a(x-h)^2+k

    in which (h, k) happens to be the vertex.
