2 (x + 2) (x - 3)

2 (x - 1) (x + 6)

2 (x - 6) (x + 1

Find the quotient.

(4ab - 8a 2 + 12ac) : 4a

b - 2a2 + 3c

b - 2a + 3c

abc

3x + 4

2x + 5|6x² + 23x + 20

6x² + 15x

8x + 20

8x + 20

0

The answer is B.

(2n³ + 4n² - 7) + (-n³ - 8n - 2)

(2n³ - n³) + 4n² - 8n - 7 - 2

n³ + 4n² - 8n - 9

The answer is B.

2x² - 10x - 12

2 (x²) - 2 (5x) - 2 (6)

2 (x² - 5x - 6)

2 (x² - 3x - 2x - 6)

2 (x (x) - x (3) - 2 (x) - 2 (3))

2 (x (x - 3) - 2 (x - 3))

2 (x - 2) (x - 3)

The answer is A.

4ab - 8a² + 12ac = 4ab - 8a² + 12ac = b - 2a + 3c

4a 4a 4a 4a

The answer is B.
