Answer:
D
Explanation:
product AB
= (x - 3)(x³ + 2x² + x - 2)
each term in the second factor is multiplied by each term in the first factor, that is
x(x³ + 2x² + x - 2) - 3(x³ + 2x² + x - 2) ← distribute both parenthesis
=
+ 2x³ + x² - 2x - 3x³ - 6x² - 3x + 6 ← collect like terms
=
- x³ - 5x² - 5x + 6
