    Answer:

    – 4x³ – 33x² + 31x – 3

    Step-by-step explanation:

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

    x²(- 4x + 3) + 9x(- 4x + 3) – 1 (- 4x + 3) ← distribute all 3 parenthesis

    = – 4x³ + 3x² – 36x² + 27x + 4x – 3 ← collect like terms

    = – 4x³ – 33x² + 31x – 3
