/x-1/ +/x+2/ +/x-3/ =14
\(\Leftrightarrow\)/x-1/ + /x-3/ +/x+2/ =14
\(\Leftrightarrow\)/x-1/ +/3-x/ +/x+2/ =14
\(\Leftrightarrow\)/x-1+3-x/ +/x+2/ =14
\(\Leftrightarrow\)2 +/x+2/ =14
\(\Leftrightarrow\)/x+2/ -12 =0
\(\Rightarrow\)\(\orbr{\begin{cases}x+2=12\\x+2=-12\end{cases}}\)
\(\Rightarrow\)\(\orbr{\begin{cases}x=10\\x=-14\end{cases}}\)
Vậy S ={ 10 ;-14 }
