x+2\x-2=x+5\x-1 amplificam cu x pt a avea acrlasi numitor

x^2+2-2x=x^2+5-x    x^2 se simplifica 
2-2x=5-x  
-2x+x=5-2
-x=3

[tex] \frac{x+2}{x-2} = \frac{x+5}{x-1} ..[/tex] la prima amplifici cu x-1,la a doua cu x-2
=>[tex](x+2)(x-1)=(x+5)(x-2) => x^{2} +x-2= x^{2} +3x-10 => [/tex][tex]x-2=3x-10=>8=2x=>x=4[/tex]
