Consider the given expression :-

$\tt \: = > \frac{ {x}^{2} - 1}{5} \: \: at \: \: x = - 1$

Now,

$\tt \: Put \: x = - 1 \: \: in \: \: \frac{ {x}^{2} - 1}{5} \: \: is$

$\tt = > \frac{( { - 1)}^{2} - 1}{5}$

$\tt \: = > \frac{1 - 1}{5}$

$\tt \: = > 0$

$\tt \green{Therefore , \pink{0} \: is \: the \: Ans }$
