To divide the expression (4k^2-29k-24)/(k^2-13k+40) by (4k^2+15k+9)/(5k^3-25k^2-3k+15), we can simplify the division by multiplying the first expression by the reciprocal of the second expression.

First, factorize the expressions: (4k^2-29k-24) can be factored as (4k+3)(k-8) (k^2-13k+40) can be factored as (k-5)(k-8) (4k^2+15k+9) can be factored as (4k+3)(k+3) (5k^3-25k^2-3k+15) can be factored as (k-1)(5k^2+3)

Now, we can rewrite the division as multiplication: (4k+3)(k-8) / (k-5)(k-8) * (5k^2+3) / (k-1)

Next, we can cancel out the common factors: (4k+3) / (k-5) * (5k^2+3) / (k-1)

Finally, we can multiply the numerators and denominators: (4k+3)(5k^2+3) / (k-5)(k-1)

This is the simplified expression after dividing (4k^2-29k-24)/(k^2-13k+40) by (4k^2+15k+9)/(5k^3-25k^2-3k+15).
