Differentiate (2x+5)^2*(x-4) with respect to x
-----------
The Chain Rule:
--> 2*(2x+5)*2*(x-4) + (2x+5)^2*x

.

I came to show you how to do it correctly: 


You should apply first the rule of differentiating a product


      (uv)' = u'*v + u*v'


and then apply the chain differentiating rule :


       ((2x+5)^2*(x-4)) =  2*(2x+5)*2*(x-4) + (2x+5)^2.   ANSWER


I mean :  the  correct  answer.
