DSolve[y[x]*(1 + x*y[x])*(1 + x^2*y[x]^2) + x*(1 - x*y[x])*(1 - x^2*y[x]^2)*y'[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> -x^(-1)}, Solve[C[1] + 2*Log[y[x]] + 1/(x*y[x]) == x*y[x], y[x]]}
Maple raw input
dsolve(x*(1-x*y(x))*(1-x^2*y(x)^2)*diff(y(x),x)+(1+x*y(x))*(1+x^2*y(x)^2)*y(x) = 0, y(x),'implicit')
Maple raw output
y(x) = -1/x, 1/2*(-2*ln(x*y(x))*x*y(x)-1+x^2*y(x)^2-2*x*(_C1-ln(x))*y(x))/x/y(x) = 0
