x/(x+2)-2/(x-1)<0

\frac{x}{x + 2} - \frac{2}{x - 1} < 0

- 2 < x < - 1 or 1 < x < 4

Solution steps

\frac{x}{x + 2} - \frac{2}{x - 1} < 0

Rewrite in standard form

\frac{x ^{2} - 3 x - 4}{( x + 2 ) ( x - 1 )} < 0

Factor

\frac{x ^{2} - 3 x - 4}{( x + 2 ) ( x - 1 )} : \frac{( x + 1 ) ( x - 4 )}{( x + 2 ) ( x - 1 )}

\frac{( x + 1 ) ( x - 4 )}{( x + 2 ) ( x - 1 )} < 0

Identify the intervals

- 2 < x < - 1 or 1 < x < 4
