Question

name the discriminant in the quadratic equations

Answer 1

your answer for above question

Answer 2

suppose we have a quadratic equation
$a {x}^{2} + bx + c = 0$
then the discriminant (d) is given by
$d = \sqrt{ {b}^{2} - 4ac}$
descriminant plays role in defining nature of roots
if d>0....real roots
if d=0....equal roots
if d<0....imaginary roots
