Question

Решите неравенство: (x + 1)(x − 3)(x + 4) < 0

Answer 1

$x+1=0$
$x-3=0$
$x+4=0$
$x=-1$
$x=3$
$x=-4$
$x\ \textless \ -4$
$-4\ \textless \ x\ \textless \ -1$
$-1\ \textless \ x\ \textless \ 3$
$x\ \textgreater \ 3$
$x\ \textless \ -4$ истинно
$-4\ \textless \ x\ \textless \ -1$ ложно
$-1\ \textless \ x\ \textless \ 3$ истинно
$x\ \textgreater \ 3$ ложно
$x\ \textless \ -4$ или $-1\ \textless \ x\ \textless \ 3$
