How do you divide #(x^3-1)/(x^2+1) div (9x^2+9x+9)/(x^2-x)#? Algebra Rational Equations and Functions Division of Rational Expressions 1 Answer Sonnhard Jun 22, 2018 #x(x-1)/9# Explanation: Note that #x^3-1=(x-1)(x^2+x+1)# we get #(x^3-1)/(x-1)*(x(x-1))/(9(x^2+x+1))#= #((x-1)(x^2+x+1)*x*(x-1))/(9(x^2+x+1)(x-1))=(x(x-1))/9# Answer link Related questions What is Division of Rational Expressions?
