Answer:

(8.6533,0)

(0.3467,0)

Step-by-step explanation:

We're going to have to use the quadratic formula

[tex]\frac{-b+\sqrt{b^2-4*a*c} }{2a}[/tex] (think of the addition sign in front of the -b as a plus or minus)

[tex]\frac{-(-18)+\sqrt{-18^2-4*2*6} }{2*2}\\\frac{18+\sqrt{276}}{4}\\8.6533\\\\\frac{18-\sqrt{276}}{4}\\.3467[/tex]
