What am I doing wrong here? I have applied the chain rule, but the answer is actually 92/9.

How do you set up the chain rule? And where is 92/9 coming from? I keep getting -184/9.
phys251 is right. Plugging in x=2 gives -184/9.
Thanks guys, it appears I forgot to multiply 3 by the "u" prime.. Anyways, I think the back of the textbook is wrong because im getting -184/9 aswell.
