Answer:
6
+ 5x³ - 9x² + 2x
Step-by-step explanation:
Given
(3x² - 2x)(2x² + 3x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
= 3x²(2x² + 3x - 1) - 2x(2x² + 3x - 1) ← distribute both parenthesis
= 6
+ 9x³ - 3x² - 4x³ - 6x² + 2x ← collect like terms
= 6
+ 5x³ - 9x² + 2x
