Answer:

12a^3 + 2a^2 + 23a + 18

Explanation:

Please use the " ^ " symbol to represent exponentiation: 4a^2 – 2a + 9.

Now carry out the multiplication as follows:

First, multiply each term in 4a^2 – 2a + 9 by 3a: 12a^3 - 6a^2 + 27a.

Next, multiply each term in 4a^2 – 2a + 9 by 2: 8a^ 2 - 4a + 18.

Now combine like terms:

12a^3 - 6a^2 + 27a

8a^ 2 - 4a + 18

---------------------------------

12a^3 + 2a^2 + 23a + 18
