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