How do you solve #x^2-6x+9<0#? Precalculus Solving Rational Inequalities Polynomial Inequalities 1 Answer Konstantinos Michailidis Jul 25, 2016 We have that #x^2-6x+9=(x-3)^2>=0# hence the inequality #x^2-6x+9<0# has no solutions. As you can see from the graph of #x^2-6x+9# there no values of x for which the inequality #x^2-6x+9<0# holds.
