So, the zeros are 1, (-1).

ALITER:
By the Quadratic formula:

Here:
a = coefiicient of        (Here : 1)
b = coefficient of x                              (Here : 0)
c = constant                                       (Here : -1)
Solving:

but actually the number of zeroz are 0
no real number of zeros
@helpinghand
Read it as (x^2 + 0.x - 1) and solve it by the Quadratic formula. You will get the same answer.
I will add that.....just a minute
