    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.
