Answer:

3x³ - 7x² - 2x + 8

Step-by-step explanation:

(x + 1)(3x² - 10x + 8)

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

x(3x² - 10x + 8) + 1 (3x² - 10x + 8) ← distribute parenthesis

= 3x³ - 10x² + 8x + 3x² - 10x + 8 ← collect like terms

= 3x³ - 7x² - 2x + 8
