Answer:
C −2a^3+9a^2+45a+6ab^2+18b^2 
Step-by-step explanation:
(a+3) ( −2a^2+15a+6b^2)
Distribute the a to the large term in parentheses and the 3 to the large term in parentheses
 a ( −2a^2+15a+6b^2)+3  ( −2a^2+15a+6b^2)
 −2a^3+15a^2+6ab^2 −6a^2+45a+18b^2
Combine like terms
 −2a^3+15a^2−6a^2+6ab^2 +45a+18b^2
-2 a^3 + 9 a^2 + 6 a b^2 + 45 a + 18 b^2
