    Answer:

    • No, incorrect

    Step-by-step explanation:

    Given

    • Q(s) = -4s^3 + 7s^2 – 24;
    • s = -4 and 1

    Verifying zeroes

    Q(-4) =

    • -4(-4)^3 + 7(-4)^2 – 24 =
    • 256 + 112 – 24 =
    • 344
    • Incorrect as 344 ≠ 0

    Q(1) =

    • -4(1)^3 + 7(1)^2 – 24 =
    • -12 + 7 – 24 =
    • -29
    • Incorrect as -29 ≠ 0
