    3x³ - 13x² + 7x - 12

    Step-by-step explanation:

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

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

    = 3x³ - x² + 3x - 12x² + 4x - 12 ← collect like terms

    = 3x³ - 13x² + 7x - 12
