Answer:

x^2 - 1/5 where, x = -1

Put the value in the expression

(-1)^2 - 1/5

1 - 1/5

=4/5

Answer 2

$Given \: algebraic \: expression : x^{2} - \frac{1}{5}$

$If \: x = -1 \:then \\\red{The \: value \:of \: x^{2} - \frac{1}{5}} \\= (-1)^{2} - \frac{1}{5} \\= 1 - \frac{1}{5} \\= \frac{5-1}{5} \\= \frac{4}{5}$

Therefore.,

$\red{ Required \: value } \green { = \frac{4}{5} }$
