This is a continuation of a problem which I have the derivative of. It is -2x^3+6x^2-6x+2/(x^3-3x^2+2x)^2
The question is to find the second derivative but I keep getting caught up in the simplifying areas around it after taking the derivative of it. Can anyone help me out by even posting a couple of main steps and the final answer part?
I'm not sure if I'm doing it right either.
