Don't know the steps in finding this derivative.
But the derivative is
Now simplify:
The answer is:
log(x) - 1 /log(x) - 1 log(x)\ x *|---------- + ------| \ x x /
-1 + log(x) / 2 \ x *\3 + (-1 + 2*log(x)) - 2*log(x)/ ---------------------------------------------- 2 x
-1 + log(x) / 3 \ x *\-8 + (-1 + 2*log(x)) + 4*log(x) - 3*(-1 + 2*log(x))*(-3 + 2*log(x))/ ----------------------------------------------------------------------------------- 3 x
