Answer:
The general form of a quadratic equation is ax2 + bx + c = 0
b2 - 4ac is called the discriminant of the quadratic equation and we can decide whether the real roots exist or not based on the value of the discriminant.
We know that,
(i) Two distinct real roots, if b2 - 4ac > 0
(ii) Two equal real roots, if b2 - 4ac = 0
(iii) No real roots, if b2 - 4ac < 0
