Your equation returns
(c_1*x^2+c_2*x+c_2)/(c_1*x+c_2)
with the latest Xcas. You can get your solution with c_2=1.
You are missing y=x with your general solution.

thank you!
I'll try, hoping in the future to have the XCas feature also in the Prime...


(I wonder if there is a regular version of XCas that run into Mac OS X (without Windows emulator): I need it...)
