Answer:

3 $x^{4}$ - 10x³ - x² - 11x + 6

Step-by-step explanation:

Each term on the upper row is multiplied by each term on the lower row.

This can be expressed as

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

= 3 $x^{4}$ - 15x³ + 6x² + 2x³ - 10x² + 4x + 3x² - 15x + 6 ← collect like terms

= 3 $x^{4}$ - 10x³ - x² - 11x + 6
