    10x² - 8x - 24

    Step-by-step explanation:

    Given

    (2x - 4) (6 + 5x)

    Each term in the second factor is multiplied by each term in the first factor, that is

    2x (6 + 5x) - 4 (6 + 5x) ← distribute both parenthesis

    = 12x + 10x² - 24 - 20x ← collect like terms

    = 10x² - 8x - 24
