    C

    Step-by-step explanation:

    Given

    (2x + 5) (7 - 4x)

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

    = 2x (7 - 4x) + 5 (7 - 4x) ← distribute both parenthesis

    = 14x - 8x² + 35 - 20x ← collect like terms

    = - 8x² - 6x + 35 → C
