Question

The quadratic 2x2 + 6x + 3 has what type of roots?

Answer 1

Well yes. There are 2 real roots but they are not positive.

Answer 2

Check the discriminant:
b^2 - 4ac

a = 2, b = 6, c = 3

discriminant > 0, you have two real roots
discriminant = 0, you have one real root
discriminant < 0, you have two complex roots

Answer 3

or, sometimes, I think the "one real root" is also called a "double root"
