Question

if Discriminant = 0 , then the quadratic equation has


(a) no real roots
(b) equal roots
(c) distinct roots
(d) none of these
​

Answer 1

$☆here \: is \: ur \: answer☆\:$

The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation. A positive  discriminant  indicates that the quadratic has two distinct real number solutions. A discriminant of zero indicates that the quadratic has a repeated real number solution.

Answer 2

A quadratic equation with real coefficients can have either one or two distinct real roots, or two distinct complex roots. In this case the discriminant determines the number and nature of the roots. There are three cases: If the discriminant is positive, then there are two distinct roots.
