Answer:1,-1
Step-by-step explanation:
x ^2 −1=0
⇒x ^2 −1 ^2 =0
⇒(x−1)(x+1)=0 (∵a ^2 −b ^2 =(a−b)(a+b))
⇒(x−1)=0,(x+1)=0
⇒x=1,x=−1

Answer :
Hey buddy !
Here is your answer...
Polynomial :
P(x) = x^2 - 1 = 0 ( given)
= x^2 - (1)^2 = 0
= (x+1) (x-1) = 0
[ Formula used = a^2 - b^2 = (a+b ) (a-b) ]
= ( x+1) =0. (x-1) = 0
= x = -1. x = 1
So, the zeroes are - 1 and 1
