Question

Complete factorization

Answer 1

Answer:

A. 2x + 1

Step-by-step explanation:

6x³ - 15x² - 9x

3x (2x² - 5x - 3)

3x (2x² + x - 6x - 3)

3x (x (2x + 1) - 6x - 3)

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

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

one of the factor of the complete factorization is A. 2x + 1

Answer 2

Answer:

$\tt{}A. \:2x + 1$

Step-by-step explanation:

$\tt{}6 {x}^{3} - 15 {x}^{2} - 9x$

$\tt{}3x \times ( {2x}^{2} - 5x - 3)$

$\tt{}3x \times ( {2x}^{2} + x - 6x - 3)$

$\tt{}3x \times (x \times (2x + 1) \times3 (2x + 1))$

$\tt{}3x \times (2x + 1) \times (x - 3)$
