    Work out the values of a, b and c

    I feel stupid: six years of high-school math and I still can't solve this problem.
    Hopefully, there is someone on this forum who can!

    Problem:

    Let V(p) = ap2+ bp + c

    V(0) = 0 and V(1) = 0.

    Work out (without a calculator) the values of a, b and c.

    Re: Work out the values of a, b and c

    V(0) = a(0)^2+b(0)+c = c = 0

    now you do the same for V(1) and then solve for a and b

    However, in general, and in this problem in particular, two equations are not enough to determine three values. There are an infinite number of values of a and b that, with c= 0, satisfy these conditions.
