Multiply and simplify. (2x - 1) (6x - 7)

A)

12x2 - 20x - 7

B)

12x2 - 2x + 7

C)

12x2 + 20x + 7

D)

12x2 - 20x + 7

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
