Chain Rule

[Blitze105]

Hello,
This is the 3rd chain rule question i have had.. and it is a dreaded EVEN number problem. could some one check it to see if i have this process down. If not i'd preferably learn what i did wrong before i do the next 100 or so...

Good work.

Only one small detail. I think there should be a negative sign in front of the 2.

\(\displaystyle \frac{-2(x+5)(x^{2}+10x-2)}{(x^{2}+2)^{3}}\)

Ah, yes it should be there. Thank you for checking my work
