What is the standard form of #y= (3x-1)(7x-2)(x+1) #? Algebra Polynomials and Factoring Polynomials in Standard Form 1 Answer Loweena Gonasegaran Feb 17, 2018 #21x^3+20x^2+x+2# Explanation: Given: #y=(3x-1)(7x-2)(x+1)# First, solve #(3x-1)# and #(7x-1)# by expanding them. #(3x-1)(7x-2)# #=21x^2-6x-7x+2# #=21x^2-x+2# Now,solve #(21x^2-x+2)# and #(x+1)# by expanding them. #(21x^2-x+2)(x+1)# #=21x^3+21x^2-x^2-x+2x+2# #=21x^3+20x^2+x+2# Answer link Related questions What is a Polynomial?
