For real and equal roots
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. Some of the examples of real roots are: - 3, 2, 5 ...
