x^2 −x^2 =x^2 −x^2   (x−x)(x+x)=x(x−x)  x−x=x  2x=x  2=1
$${x}^{\mathrm{2}} −{x}^{\mathrm{2}} ={x}^{\mathrm{2}} −{x}^{\mathrm{2}} \\ $$$$\left({x}−{x}\right)\left({x}+{x}\right)={x}\left({x}−{x}\right) \\ $$$${x}−{x}={x} \\ $$$$\mathrm{2}{x}={x} \\ $$$$\mathrm{2}=\mathrm{1} \\ $$

x−x = 0 we can′t divide it
$${x}−{x}\:=\:\mathrm{0}\:{we}\:{can}'{t}\:{divide}\:{it} \\ $$$$ \\ $$
