Question

Решить неравенство (5x+1)/(x-2)<0

Answer 1

$(5x+1)=0$
$(x-2)=0$
$5x=-1$
$x=- \frac{1}{5}$
$x=2$
$x\ \textless \ - \frac{1}{5}$
$- \frac{1}{5} \ \textless \ x\ \textless \ 2$
$x\ \textgreater \ 2$
$x\ \textless \ - \frac{1}{5}$ ложно
$- \frac{1}{5} \ \textless \ x\ \textless \ 2$ истинно
$x\ \textgreater \ 2$ ложно
$- \frac{1}{5} \ \textless \ x\ \textless \ 2$
