How do you differentiate #f(x)= (2x+1)(4-x^2)(1+x^2) # using the product rule? Calculus Basic Differentiation Rules Product Rule 1 Answer ali ergin Jul 21, 2016 #d f(x)=[2(4-x^2)(1+x^2)-2x(2x+1)(1+x^2)+2x(2x+1)(4-x^2)] d x# Explanation: #y=a*b*c" ; "y^'=a'*b*c+b^'*a.c+c^'*a*b# #f(x)=(2x+1)(4-x^2)(1+x^2)# #(d f(x))/(d x)=2(4-x^2)(1+x^2)-2x(2x+1)(1+x^2)+2x(2x+1)(4-x^2)# #d f(x)=[2(4-x^2)(1+x^2)-2x(2x+1)(1+x^2)+2x(2x+1)(4-x^2)] d x# Answer link Related questions What is the Product Rule for derivatives?
