Question

When factored completely, the expression 6x3 – 5x2 – 13x + 12 is

equivalent to
a. (2 – 1)(2x - 3)(3x + 4)
b. (x + 1)(2x + 3)(3x + 4)
c. (x + 1)(2x − 3)(3x – 4)
d. (x - 1)(2x + 3)(3x – 4)

Answer 1

( x - 1 )( 2x + 3 )( 3x - 4 )

Explanation:

Hope this helps!

Answer 2

d. (x - 1)(2x + 3)(3x - 4)

Explanation:

6x³ - 5x² - 13x + 12

6x³ + x² - 12x - 6x² - x + 12

x(6x² + x - 12) - 1(6x² + x - 12)

(x - 1)(6x² + x - 12)

(x - 1)(6x² + 9x - 8x - 12)

(x - 1)(3x(2x + 3) - 4(2x + 3))

(x - 1)(2x - 3)(3x - 4)
