    Answer:

    x= 3 +[tex]\sqrt{23}[/tex], 3 -[tex]\sqrt{23}[/tex]

    Step-by-step explanation:

    You use the quadratic formula to get x= [tex]\frac{18+6\sqrt{23} }{6} ,\frac{18-6\sqrt{23} }{6}[/tex]

    Then you simplify and get the answers x= 3 +[tex]\sqrt{23}[/tex], 3 -[tex]\sqrt{23}[/tex]
