If the discriminant of the quadratic equation is +ve then the roots are:

If the discriminant of a quadratic equation ax^2 + bx + c = 0 is positive (i.e., b^2 – 4ac > 0), then the roots of the quadratic equation are real and unequal.

This is because the discriminant is used to determine the nature of the roots of a quadratic equation. Specifically, if the discriminant is positive, then the roots of the quadratic equation are real and unequal. This is because in this case, the quadratic formula (-b ± sqrt(b^2 – 4ac)) / 2a will yield two distinct real solutions for x.
