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

$p(x)=x^{2}-1 ; x=1,-1$

Option A
Option B
Option C
Option D

Solution

If $x=1$ and $x=-\,1$ are zeroes of polynomial $p(x)=x^{2}-1,$ then $p(1)$ and $p(-1)$ should be $0$ .

Here, $p (1)=(1)^{2}-1=0,$ and $p (-1)$

$=(-1)^{2}-1=0$

Hence, $x=1$ and $-1$ are zeroes of the given polynomial.
