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

1223 - 2a + 18

12a3 + 6a + 9

12a3 - 6a + 23a + 18

1223 + 2a + 23a + 18

The answer is 12a^3+2a²+23a+18 ...

Step-by-step explanation:

The given terms are:

(3a + 2) (4a² - 2a + 9)

Now multiply each value of second bracket with the first bracket:

=4a² (3a+2) - 2a (3a+2) + 9 (3a+2)

=12a^3+8a²-6a²-4a+27a+18

Solve the like terms:

=12a^3+2a²+23a+18

Therefore the answer is 12a^3+2a²+23a+18 ...
