\(\left|x+1\right|và\left|x+2\right|\ge0\)
\(\Rightarrow\orbr{\begin{cases}\left(x+1\right)+\left(x+2\right)=3\\\left(x+1\right)+\left(x+2\right)=-3\end{cases}}\)
\(\orbr{\begin{cases}2x+3=3\\2x+3=-3\end{cases}}\)
\(\orbr{\begin{cases}2x=0\\2x=-6\end{cases}}\)
\(\orbr{\begin{cases}x=0\\x=-3\end{cases}}\)
\(\left|x+1\right|+\left|x+2\right|=3\)
Xét \(x+1\ge0;x+2\ge0\Leftrightarrow x\ge-1;x\ge-2\Rightarrow x\ge-1\) ta có : \(\hept{\begin{cases}\left|x+1\right|=x+1\\\left|x+2\right|=x+2\end{cases}}\)
\(\Rightarrow\left|x+1\right|+\left|x+2\right|=3\Leftrightarrow x+1+x+2=3\Leftrightarrow2x+3=3\Rightarrow x=0\)(TM)
Xét \(x+1\le0;x+2\ge0\Leftrightarrow-2\le x\le-1\) ta có : \(\hept{\begin{cases}\left|x+1\right|=-x-1\\\left|x+2\right|=x+2\end{cases}}\)
\(\Rightarrow\left|x+1\right|+\left|x+2\right|=3\Leftrightarrow-x-1+x+2=3\Leftrightarrow1=3\) (loại)
Xét \(x+1\le0;x+2\le0\Leftrightarrow x\le-1;x\le-2\Leftrightarrow x\le-2\) ta có : \(\hept{\begin{cases}\left|x+1\right|=-x-1\\\left|x+2\right|=-x-2\end{cases}}\)
\(\Rightarrow\left|x+1\right|+\left|x+2\right|=-x-1-x-2=-2x-3=3\Rightarrow x=-3\)(TM)
Vậy \(x=\left\{-3;0\right\}\)
