How do you use the quotient rule to differentiate #(2x+1)/(x^2-1)#? Calculus Basic Differentiation Rules Quotient Rule 1 Answer Tony B Jan 20, 2016 #(dy)/(dx)= (-2(x^2+x+1))/(x^2-1)^2# Explanation: Standard form: # (d)/dx (u/v)=(dy)/(dx)= (v (du)/(dx) - u(dv)/(dx))/v^2# Given:#color(white)(..) y=(2x+1)/(x^2-1)# #(dy)/(dx)= ((x^2-1)2-(2x+1)2x)/(x^2-1)^2# #(dy)/(dx)= (2x^2-2-4x^2-2x)/(x^2-1)^2# #(dy)/(dx)= (-2x^2-2x-2)/(x^2-1)^2# But #-2x^2-2x-2= -2(x^2+x+1)# #(dy)/(dx)= (-2(x^2+x+1))/(x^2-1)^2# Answer link Related questions What is the Quotient Rule for derivatives?
