# Solution for Verify Whether the Indicated Numbers Are Zeroes of the Polynomials Corresponding to Them in the Following Cases F(X)=X^2- 1,X=1,-1 - CBSE Class 9 - Mathematics

ConceptZeroes of a Polynomial

#### Question

Verify whether the indicated numbers are zeroes of the polynomials corresponding to them in the following cases

f(x)=x^2- 1,x=1,-1

#### Solution

f(x)=x^2- 1,x=1,-1

we have f(x)x^2 -1

put x=and  x=-1

⇒ f(1)=(1)^2 -1   and f(-1)=(-1)^2-1

=1-1=0                        =1-1=0

∴=1,-1are the roots of f(x)=x^2-1

Is there an error in this question or solution?
