By using the quotient rule, did you mean like this?

Yes this was what I meant, your quotient rule is correct. However, the second last step you could have factorise (5x-2) so the final answer is (-50x-20)/((5x-2)^3).
Anyway if you have time, recheck the answer for the quotient rule. How do you arrive at 10-100x/(5x-2)^3?
