# Verify Whether the Indicated Numbers is Zeroes of the Polynomials Corresponding to Them in the Following Case: F ( X ) = 2 X + 1 , X = 1 2 - CBSE Class 9 - Mathematics

ConceptZeroes of a Polynomial

#### Question

Verify whether the indicated numbers is zeroes of the polynomials corresponding to them in the following case:

f (x) = 2x +1, x = 1/2

#### Solution

f (x) = 2x +1, x = 1/2

put x=1/2⇒ f(1/x)=2xx(1/2)+1=1+1=2≠0

∴x=1/2 is not a root of f(x)=2x+1

Is there an error in this question or solution?
