सत्यापित कीजिए कि दिखाए गए मान निम्नलिखित स्थितियों में संगत बहुपद के शून्यक हैं

$p(x)=5 x-\pi ; x=\frac{4}{5}$

Option A
Option B
Option C
Option D

Solution

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.
