    To find the zeros of a function set the function equal to zero and solve.

    f(x) = x^2 + 6x -7 = 0

    x^2 + 6x -7 = 0 Try to factor the left side

    (x +7)(x-1) = 0 now solve both factors for x

    x + 7 = 0

    x = -7

    x - 1 = 0

    x = 1

    so the zeros of the function are -7 and 1
