WebApr 22, 2024 · Nature of the Roots. For a standard quadratic equation, i.e., a x 2 + b x + c = 0, a ≠ 0, where a, b, c are real numbers. The roots (x) are: x = − b ± b 2 − 4 a c 2 a. The nature of the roots depends on b 2 − 4 a c. This quantity is called Discriminant D. Therefore, Discriminant D = b 2 − 4 a c.
