Answer:
3 - 11
- 4x³ + 3x² + x
Step-by-step explanation:
(x³ - 4x² + 1)(3x² + x)
Each term in the second factor is multiplied by each term in the first factor, that is
x³(3x² + x) - 4x²(3x² + x) + 1 (3x² + x) ← distribute parenthesis
= 3 +
- 12
- 4x³ + 3x² + x ← collect like terms
= 3 - 11
- 4x³ + 3x² + x
