Question

What is the product of (3a + 2)(4a2 – 2a + 9)?

Answer 1

Answer:

12a^3 + 2a^2 + 23a + 18    

Step-by-step 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
