Hi Rickey,

Let's calculate the discriminant. If it is greater than zero, the polynomial will have two real roots.

b^2 - 4ac a = 3, b = -1 and c = -12

(-1)^2 - 4*3*-12 = 145

since 145>0, there are

**two real roots**.Kemal G.

You will need to use the quadratic formula to figure that out. The quadratic formula is

x

_{1,2 }= (-b ± sqrt(b^2 - 4ac)) / 2aI already indicated the values of a, b and c. Can you find the roots?

It's irrational right? I just did the work and I got irrational

Yes. What are the values you got for the roots?
