Answer:
The third option
Step-by-step explanation:
Given
(a + 3)(- 2a² + 15a + 6b²)
Each term in the second factor is multiplied by each term in the first factor, that is
a(- 2a² + 15a + 6b²) + 3(- 2a² + 15a + 6b²) ← distribute both parenthesis
= - 2a³ + 15a² + 6ab² - 6a² + 45a + 18b² ← collect like terms
= - 2a³ + 9a² + 45a + 6ab² + 18b² → C
