                      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.
