Answer:

3x³ - 7x² + 6x - 2

Explanation:

Given

(x - 1)(3x² - 4x + 2)

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

x(3x² - 4x + 2) - 1 (3x² - 4x + 2) ← distribute both parenthesis

= 3x³ - 4x² + 2x - 3x² + 4x - 2 ← collect like terms

= 3x³ - 7x² + 6x - 2 ← in expanded form
