Answer:

3
x^(5) - 11
x^(4) - 4x³ + 3x² + x

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
x^(5) +
x^(4) - 12
x^(4) - 4x³ + 3x² + x ← collect like terms

= 3
x^(5) - 11
x^(4) - 4x³ + 3x² + x
