Как решать ((x+2) / (x-1)) - ((x-2) / x+1)) = 4x^2 / (x^2-1) ...

((x+2) / (x-1)) - ((x-2) / (x+1)) = 4x² / (x²-1);

((x+2) (x+1) - (x-2) (x-1)) / (x²-1) = 4x² / (x²-1);

(x²+2x+x+2-x²+2x+x-2) / (x²-1) = 4x² / (x²-1);

6x / (x²-1) = 4x² / (x²-1);

6x=4x²;

4x²-6x=0;

2x (2x-3) = 0;

x₁=0;

2x-3=0;

x₂=3/2=1.5;
