How do you solve #x+1/x=4#? Algebra Rational Equations and Functions Clearing Denominators in Rational Equations 1 Answer Sidharth Feb 19, 2016 # therefore x = 2 +-sqrt3# Explanation: #x+1/x=4# #(x^2 + 1)/x# = 4 #x^2 + 1 = 4x# #x^2 -4x + 1 = 0# #x^2 - 4x + 4 - 4 + 1 = 0# #(x-2)^2 = 3# #x - 2 = +-sqrt3# # therefore x = 2 +-sqrt3# Answer link Related questions What is Clearing Denominators in Rational Equations?
