CEVAP:

In the quadratic formula, b²–4ac is called the discriminant of the quadratic equation and we use
the symbol ? (capital Greek delta) for discriminant:
?= b²–4ac
If the discriminant is positive, then there are two distinct roots.If the discriminant is zero, then there is exactly one real root. If the discriminant is negative, then there are no real roots.
