Can someone please check me (to make sure my reasoning is sound, primarily...but always nice to have the algebra looked at as well)? d/dx [(x-2) d/dx (5-x4)] =d/dx [(x-2)(-4x^3)] =d/dx [-4x^4 + 8x^3] = -16x^3 + 24x^2

Thanks. When I can put this kind of query into wolframalpha I do, but it didn't like the syntax on this one.

Try breaking it up and just doing one derivative at a time. =)

You're too right, but I wasn't sure it would be ok to do...now I am the wiser, and I thank you.
