(C4) desolve(diff(y(x),x)=(4-2*x)/(3*y^2-5),y(x));
2 x 4 x
(D4) y(x) = - -------- + -------- + y(0)
2 2 3 y - 5 3 y - 5
it should be
2 x 4 x
(D4) y(x) = - -------- + -------- + y(0)
2 2 y - 5 y - 5

This is not a bug in desolve. As the documentation says,
desolve requires functional dependencies to be explicit --
there is no connection between the function y(x) and the
variable y. It turns out that desolve can't solve this equation,
but ode2 claims to. I don't know if its solution is correct.
