    D) 12x² - 20x + 7

    Step-by-step explanation:

    Use FOIL when multiplying 2 binomials ...

    FOIL is Firsts, Outsides, Insides, Lasts. It's the order in which you multiply the numbers in the binomials ...

    (2x - 1) (6x - 7)

    Firsts: (2x) (6x) = 12x²

    Outsides: (2x) (-7) = - 14x

    Insides: (-1) (6x) = - 6x

    Lasts: (-1) (-7) = 7

    Now add them up ...

    12x² - 14x - 6x + 7

    12x² - 20x + 7
