Answer:
(D) [tex]9k^3-3k^2-29k-12[/tex]
Step-by-step explanation:
The given expression is:
[tex](3k+4)(3k^2-5k-3)[/tex]
Upon simplifying the above expression, we get
=[tex]3k(3k^2-5k-3)+4(3k^2-5k-3)[/tex]
=[tex]9k^3-15k^2-9k+12k^2-20k-12[/tex]
Solving the like terms together, we have
=[tex]9k^3-3k^2-29k-12[/tex]
which is the required simplified form of the given expression.
Hence, option D is correct.
