(x^2+1)^2-4 x^2(x^2+1)^2-4 x^2 = (x^2+1)^2-(2 x)^2:(x^2+1)^2-(2 x)^2(x^2+1)^2-(2 x)^2 = ((x^2+1)-2 x) ((x^2+1)+2 x):(x^2-2 x+1) (x^2+2 x+1)x^2+2 x+1 = (x+1) (x+1):(x+1) (x+1) (x^2-2 x+1)(x+1) (x+1) = (x+1)^2:(x+1)^2 (x^2-2 x+1) x^2-2 x+1 = (x-1) (x-1):(x-1) (x-1) (x+1)^2(x-1) (x-1) = (x-1)^2:Ответ: (x-1)^2 (x+1)^2
