Answer 2

Answer:

product of (3a+2)((4a²-2a+9)

= 12a³+2a²+23a+18

Explanation:

Product of (3a+2)(4a²-2a+9)

=3a(4a²-2a+9)+2(4a²-2a+9)

= 12a³-6a²+27a+8a²-4a+18

Rearranging the like terms at one place, we get

= 12a³-6a²+8a²+27a-4a+18

= 12a³+(-6+8)a²+(27-4)a+18

= 12a³+2a²+23a+18

Therefore,

(3a+2)((4a²-2a+9)

= 12a³+2a²+23a+18
