What is the derivative of #(x^2-1)^3/(x^2+1)#? Calculus Basic Differentiation Rules Quotient Rule 1 Answer ali ergin May 22, 2016 #(d y)/(d x)=-2x*(x^2-1)^3/(x^2+1)^2+6x(x^2-1)^2/(x^2+1# Explanation: #d/(d x)(x^2-1)^3/(x^2+1)=?# #d/(d x) (x^2-1)^3/(x^2+1) = (3(x^2-1)^2*2x*(x^2+1)-2x(x^2-1)^3)/(x^2+1)^2# #d/(d x)(x^2-1)^3/(x^2+1)=-2x*(x^2-1)^3/(x^2+1)^2+6x(x^2-1)^2/(x^2+1)# Answer link Related questions What is the Quotient Rule for derivatives?
