Answer:
D
Step-by-step explanation:
To multiply
(5x² - 6x + 2)(4x² - 3x)
Each term in the second factor is multiplied by each term in the first factor, that is
5x²(4x² - 3x) - 6x(4x² - 3x) + 2(4x² - 3x) ← distribute parenthesis
= 20 - 15x³ - 24x³ + 18x² + 8x² - 6x ← collect like terms
= 20 - 39x³ + 26x² - 6x → D
