    Answer:

    Option B is answer.

    Step-by-step explanation:

    Hey there!

    Given;

    f(X) = X(X+5)(x-8)

    According to the factor theorem, f(X) = 0;

    Or, X(X+5)(x-8) = 0

    Either;

    x = 0

    Or;

    (x+5)= 0

    X = -5

    Or;

    (x-8)= 0

    x = 8.

    Therefore, the zeros of the polynomial are: 0,-5,8.

    Hope it helps!
