first of all it is not discrimination is is discriminant
on comparing this quadratic equation with X square + bx + c is equal to zero
is equal to 1 b is equal to 2 and C is equal to -1
as we know that discriminant is B squared minus 4 AC
the discriminant will be 2 square minus 4 = 20 that mean it has repeated roots
