    -x (2 x - 5) (3 x + 2)

    Step-by-step explanation:

    Factor the following:

    -6 x^3 + 11 x^2 + 10 x

    Factor - x out of - 6 x^3 + 11 x^2 + 10 x:

    -x (6 x^2 - 11 x - 10)

    Factor the quadratic 6 x^2 - 11 x - 10. The coefficient of x^2 is 6 and the constant term is - 10. The product of 6 and - 10 is - 60. The factors of - 60 which sum to - 11 are 4 and - 15. So 6 x^2 - 11 x - 10 = 6 x^2 - 15 x + 4 x - 10 = 2 x (3 x + 2) - 5 (3 x + 2):

    -x 2 x (3 x + 2) - 5 (3 x + 2)

    Factor 3 x + 2 from 2 x (3 x + 2) - 5 (3 x + 2):

    Answer: - x (2 x - 5) (3 x + 2)
