Answer:

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
