Answer:

None

Step-by-step explanation:

The discriminant of a quadratic equation is [tex]b^2-4ac[/tex]. In this case, that is:

[tex](-4)^2-4(3)(9)=16-108=-92[/tex]

Since the discriminant is negative, the square root will be a complex number, and this equation must have no real solutions. Hope this helps!
