Question

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

Answer 1

Answer:

Yes

Step-by-step explanation:

$p(x)=x^{2} -1$

On putting the given value of 'x' in the polynomial, we can check if it is the zero or not. If p(1)=0, then x=1 is the root.

$p(1)=1^{2} -1\\p(1)=1-1\\p(1)=0$

Hence, x=1 is the zero of the given polynomial.

Answer 2

Step-by-step explanation:

p(x)=x^2-1

and x=1

then

p(x)=1^2-1

p(1)=1-1

p(1)=0

Answer 3

Step-by-step explanation:

p(x)=x^2-1

and x=1

then

p(x)=1^2-1

p(1)=1-1

p(1)=0
