#### Question

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

`f(x) = lx + m , x = - m/l`

#### 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/l`is aroot of `f(x)=lx=m`

Is there an error in this question or solution?
