Step-by-step explanation:
Given
(x - 3)(x + 3)(2x - 1)
Expand (x - 3)(x + 3) = x² - 9 ← difference of squares factors, thus
= (x² - 9)(2x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
= x²(2x - 1) - 9(2x - 1) ← distribute both parenthesis
= 2x³ - x² - 18x + 9 → C
