Question

Is x=-1 a zero of the polynomial p(x)=x^2-1​

Answer 1

Step-by-step explanation:

p(x) = x² - 1

p(-1) = (-1)² - 1 = 1 - 1 = 0

so, yes (x = -1) is zero of the polynomial.

Answer 2

Answer:

yes x=-1 is the zero of the poly

Step-by-step explanation:

p(x)=x^2-1

sub x=-1 in the above polynomial

p(-1)= (-1)^2-1

= 1-1

= 0, :. x=-1 is the zero of polynomial
