    12x³ - 7x² + 11x + 14

    Step-by-step explanation:

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

    3x (4x² - 5x + 7) + 2 (4x² - 5x + 7) ← distribute both parenthesis

    = 12x³ - 15x² + 21x + 8x² - 10x + 14 ← collect like terms

    = 12x³ - 7x² + 11x + 14
