    Minimum p[oint is at x=\frac{a}{2} which givesyou the value of a, then using this in the equation and putting y=-4 will give b.

    Why not? You've found the values of a and b, yeah? Now just sub these values into the equation
    y = x^(2) -ax - b

    Differentiate
    Put the value x=1 into the differential and use they fact that it is a turning point to find a
    Now that you have a use the original equation and the point (1,-4) to find b

    As I pointed out when I replied to your PM

    This seems to be way above your current skill level
