Question

verify whether X=1, X=-1 are zeros of polynomial x^2-1​

Answer 1

p(X)= x²-1

p(1)= (1)²-1

= 1-1

= 0

p(-1)= (-1)²-1

= 1-1

= 0

since the remainder is coming 0 in both the cases

therefore both are the zeros of the polynomial (x²-1)

Answer 2

Yes they are the zeros of the polynomial.
