WebApr 9, 2024 · The quadratic equation has two equal real roots if D = 0. This is because the roots of D = 0 are provided by x = \[\frac{-b\pm \sqrt{0}}{2a}\] and 0 would be the square root. The equation thus becomes x = −b/2a, which is a single number. When a quadratic equation's discriminant is zero, it has only one real root. WebSuppose a x 2 + b x + c = 0 is a quadratic equation and D = b 2 – 4 a c is the discriminant of the equation such that: If D = 0, then the roots of the equation are real and equal numbers. If D > 0, then the roots are real and unequal. If D < 0, then the roots are complex, i.e. not real roots.
