Question

Verify whether the following are the zeroes of the polynomial :
p(x) =x2-1 where x = -1,3​

Answer 1

Answer:

-1 is the zero of p(x) but 3 is not zero of p(x)

Step-by-step explanation:

P(x) =x^2-1

P(-1)=(-1)^2-1

P(-1)=1-1

P(-1)=0

P(3)=(3)^2-1

P(3)=9-1

P(3)=8

Answer 2

Step-by-step explanation:

verification of zeroes

putting value x=-1

p(x)=x²-1

=(-1)²-1

=1-1

=0

so,-1is one of the root of this polynomial

now,

putting value x=3

p(x)=x²-1

=3²-1

=9-1

=8(8≠0)

so,3 is not a root of this polynomial
