The discriminant in the quadratic equation is the term B2-4AC. This is the part under the square root sign, with the full form being (-B +/- SquareRoot (B2-4AC)) / 2A.
If the original poloynomial is 7x2 - x + 1 = 0, then A=7, B=-1, and C=1, so the discriminant is -27. Since this is negative, there are two complex conjugate roots.
