Question

if D is the discriminant of a quadratic equation then the roots are imaginary if​

Answer 1

Answer:

When a, b, and c are real numbers, a ≠ 0 and the discriminant is negative, then the roots α and β of the quadratic equation ax2 + bx + c = 0 are unequal and not real. In this case, we say that the roots are imaginary
