Ta có các trường hợp sau:
+TH1: \(\left\{{}\begin{matrix}x+3>0\\x-2< 0\end{matrix}\right.\)\(\Leftrightarrow\left\{{}\begin{matrix}x>-3\\x< 2\end{matrix}\right.\)\(\Leftrightarrow-3< x< 2\)
+TH2: \(\left\{{}\begin{matrix}x+3< 0\\x-2>0\end{matrix}\right.\)\(\Leftrightarrow\left\{{}\begin{matrix}x< -3\\x>2\end{matrix}\right.\) (vô lý)
Vậy -3<x<2
