    6 (x-4) (x+3)

    Step-by-step explanation:

    6x^2 - 6x - 72

    factor out a 6

    6 (x^2 - x - 12)

    What 2 number multiply to - 12 and add to - 1

    -4*3 = - 12

    -4+3 = - 1

    6 (x-4) (x+3)

    C. x - 4

    Step-by-step explanation:

    The best way to do this is to first take out GCF

    6 (x² - x - 12)

    Then we factor

    6 (x - 4) (x + 3)

    We can now see our answer.
