    (p - 12) (p + 2)

    Step-by-step explanation:

    (p-5) ² - 49 =

    = (p - 5 - 7) (p - 5 + 7)

    = (p - 12) (p + 2)

    a² - b² = (a - b) (a + b)

    a = p - 5

    b = 49

    (p - 12) (p + 2) or

    p^2 - 10p - 24.

    Step-by-step explanation:

    We use the Difference of 2 Squares Identity.

    a^2 - b^2 = (a - b) (a + b).

    So (p - 5) ^2 - 49

    = (p - 5 - 7) (p - 5 + 7)

    = (p - 12) (p + 2)

    = p^2 - 10p - 24.
