Verify whether the following are zeroes of the polynomial, indicated against them.
$p(x)=lx+m,\,\, x=-\,\frac{m}{l}$
If $x=\frac{-m}{l}$ is a zero of polynomial $p(x)=lx+m,$ then should be $0 .$
Here, $p\left(\frac{-m}{l}\right)=l\left(\frac{-m}{l}\right)+m=-m+m=0$
Therefore, $x=\frac{-m}{l}$ is a zero of the given polynomial.
