Question

the square of a number added to 2 divided by the square of the same number subtracted by 2 gives 198/201. find the number?
$\frac{a { }^ {2} + 2}{a {}^{2} - 2 } = \frac{198}{201} \\ find \: the \: value \: of \: a$

Answer 1

I think the value of a is 14 but I am not sure
according to me
a^2+2=198
a^2=198-2=196
a=under root 196
=14
but I'm not sure about this answer
