[tex]y=\sqrt{x^2+1}-1[/tex](adsbygoogle = window.adsbygoogle || []).push({});

how do we know that there is a subtraction of two close numbers thus making loss of significance?

there is no close numbers there is variable X

it could give use a close result or otherwise

and why multiplying and dividing by [tex]y=\sqrt{x^2+1}+1[/tex]

makes it go away?
