# Verify Whether the Indicated Numbers is Zeroes of the Polynomials Corresponding to Them in the Following Case: F ( X ) = L X + M , X = − M L - 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) = lx + m , x = - m/1

#### Solution

f ( x) = lx + m and x = - m/l

put x=-^m/l ⇒f ( ^-m/l)=lxx(^-m/l)+m=-m+m=0

∴x=-m/lis aroot of f(x)=lx=m

Is there an error in this question or solution?
