How do you find the derivative of #y=(3x-4)(5x+1)#? Calculus Basic Differentiation Rules Product Rule 1 Answer Shwetank Mauria Apr 10, 2016 #d/dx{(3x-4)(5x+1)}=30x-17# Explanation: #d/dx{(3x-4)(5x+1)}# = #(3x-4)d/dx(5x+1)+(5x+1)d/dx(3x-4)# = #(3x-4)*5+(5x+1)*3# = #15x-20+15x+3# = #30x-17# Answer link Related questions What is the Product Rule for derivatives?
