Solve for x
x=-\frac{4\left(1-m\right)}{m\left(m-2\right)}
m\neq 2\text{ and }m\neq 0
Solve for m
\left\{\begin{matrix}m=\frac{\sqrt{x^{2}+4}+x+2}{x}\text{; }m=\frac{-\sqrt{x^{2}+4}+x+2}{x}\text{, }&x\neq 0\\m=1\text{, }&x=0\end{matrix}\right.

m^{2}x+4=2mx+4m
Use the distributive property to multiply 2m by x+2.
m^{2}x+4-2mx=4m
Subtract 2mx from both sides.
m^{2}x-2mx=4m-4
Subtract 4 from both sides.
\left(m^{2}-2m\right)x=4m-4
Combine all terms containing x.
\frac{\left(m^{2}-2m\right)x}{m^{2}-2m}=\frac{4m-4}{m^{2}-2m}
Divide both sides by m^{2}-2m.
x=\frac{4m-4}{m^{2}-2m}
Dividing by m^{2}-2m undoes the multiplication by m^{2}-2m.
x=\frac{4\left(m-1\right)}{m\left(m-2\right)}
Divide -4+4m by m^{2}-2m.
