Question

whether the following are zeros of the polynomial indicated against them p(x)=x^2 - 1,x= 1,-1​

Answer 1

Answer:

${x}^{2} - 1$

Put x =1

${1}^{2} - 1 = 0$

Put x=(-1)

${ - 1}^{2} - 1 = 2$

Hope it helps

Answer 2

Yes

Step-by-step explanation:

If these were the zeros of the polynomial then p(x)=0.

•putting x=1:-

p(x)=x^2-1

=1^2-1

=1-1

=0

Hence it is the zero of p(x)

•putting x= -1

p(x)=x^2-1

=(-1)^2-1

=1-1

=0

Hence it is also th zero of p(x)
