    Step-by-step explanation:

    We have the original equation n ^ 2 + 5 * n - 24, when factoring we have:

    (n + 8) * (n - 3)

    Now by replacing the values:

    n = 0

    0 ^ 2 + 5 * 0 - 24 = - 24

    (0 + 8) * (0 - 3) = - 24

    n = 1

    1 ^ 2 + 1 * 0 - 24 = - 18

    (1 + 8) * (1 - 3) = - 18

    n = 2

    2 ^ 2 + 5 * 2 - 24 = - 10

    (2 + 8) * (2 - 3) = - 10

    n = 3

    3 ^ 2 + 5 * 3 - 24 = 0

    (3 + 8) * (3 - 3) = 0

    n = 4

    4 ^ 2 + 5 * 4 - 24 = 12

    (4 + 8) * (4 - 3) = 12
