Verify whether the following are zeroes of the polynomial, indicated against them.
$p(x)=5 x-\pi, \,\,x=\frac{4}{5}$
If $x=\frac{4}{5}$ is a zero of polynomial $p(x)=5 x-n,$ then $p\left(\frac{4}{5}\right)$ should be $0 .$
Here, $p\left(\frac{4}{5}\right)=5\left(\frac{4}{5}\right)-\pi=4-\pi$
As $p\left(\frac{4}{5}\right) \neq 0$,
Therefore, $x=\frac{4}{5}$ is not a zero of the given polynomial.
