Hi,

I'm asked to differentiate $\displaystyle f(x) = 3(x^2 + 2)(4x^2 - 5x^4) - 3$.

Using the product rule, I know that $\displaystyle f'(x) = u'v + uv'$.

What I'm confused about, is what to set $\displaystyle u$ and $\displaystyle v$ to in the above function. Would $\displaystyle u=3(x^2 + 2)(4x^2 - 5x^4) $and $\displaystyle v = -3$?

Thanks,
