    3x^3 - 18x^2 + 24x

    We can factor a 3x from each term.

    3x (x^2 - 6x + 8)

    Now, we can factor the trinomial even further.

    Split the middle term.

    3x (x^2 - 2x - 4x + 8)

    3x (x (x - 2) - 4 (x - 2)

    3x (x - 4) (x - 2) is the fully factored form of the trinomial.

    The correct answer is A.
