Answer:
[tex]12a^3 +2a^2 +23a+18[/tex]
Step-by-step explanation:
[tex](3a+2)(4a^2-2a+9)[/tex]
we multiply 3a+2 inside the parenthesis to find the product
first multiply 3a inside second parenthesis
[tex]12a^3 - 6a^2 +27a[/tex]
now multiply +2 inside second parenthesis
[tex]8a^2 - 4a + 18[/tex]
Now we combine it
[tex]12a^3 - 6a^2 +27a+8a^2-4a+18[/tex]
combine like terms
[tex]12a^3 +2a^2 +23a+18[/tex]
