\(\frac{2}{x^2-2x}+\frac{1}{x}=\frac{x+2}{x-2}\)
\(\Leftrightarrow\frac{2}{x\left(x-2\right)}+\frac{1}{x}-\frac{x+2}{x-2}=0\)
\(\Leftrightarrow\frac{2}{x\left(x-2\right)}+\frac{x-2}{x\left(x-2\right)}+\frac{x\left(x+2\right)}{x\left(x-2\right)}=0\)
\(\Leftrightarrow\frac{2+x-2+x^2+2x}{x\left(x-2\right)}=0\)
\(\Leftrightarrow\frac{x^2+3x}{x\left(x-2\right)}=0\)
\(\Leftrightarrow\frac{x\left(x+3\right)}{x\left(x-2\right)}=0\)
\(\Leftrightarrow\frac{x+3}{x-2}=0\)
\(\Rightarrow x+3=0\left(x-2\ne0\right)\)
\(\Leftrightarrow x=-3\)
