Differentiate w.r.t x
(2+x)^3(2-x)^3

i firstly made them into one
so I got
(4-x^2)^6

did the chain rule the long way and got

-12(4-x^2)^5
but the answer when I checked on wolframalpha is

-6x(x^2-4)^2

I think I went wrong with the indices part but not sure why it was wrong :s

Do you mean:

because it looks like:



If it is, then simplifying will give you:



not to the power of 6.

It should be (4-x^2)^3
