\(\left|x-2,2\right|=\left|0,2+x\right|\)
Bình phương 2 vế ta có:
\(\left(\left|x-2,2\right|\right)^2=\left(\left|0,2+x\right|\right)^2\)
\(\Leftrightarrow0,04\left(25x^2-110x+121\right)=0,04\left(25x^2+10x+1\right)\)
\(\Leftrightarrow25x^2-110x+121=25x^2+10x+1\)
\(\Leftrightarrow120x=120\Leftrightarrow x=1\)
