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
