Multiply out and then use the product rule. You'll have to use the chain rule once. EDIT: Looking at your code did you mean ?

Ah ok, then yes you will. You should use the chain rule to find the derivatives of and of And then use the product rule.
So that ends up being:
Close, look at this:
oh god, I added in that 48 by mistake.
Easy mistake you did the same thing for the derivative of So just make sure you check that and then you should be good!

I enter in: And it comes back as incorrect, what do I need to do next? Wait that's not my question. I now want to know what to do with the 16x in Math anxiety
