I would use Wolfram|Alpha for this (www.wolframalpha.com). Enter: y'[x]==2(y[x]+2)^2/(x+y[x]-1)^2 When a result appears, click the "show steps" button at upper right of result pane. See http://www.wolframalpha.com/input/?i=y%27%5Bx%5D%3D%3D2%28y%5Bx%5D%2B2%29%5E2%2F%28x%2By%5Bx%5D-1%29%5E2 You can also do this within Mathematica by using the Wolfram|Alpha input interface. Click on the + sign at upper left of an input cell, select Wolfram Alpha query, and give the same input I showed above. Daniel Lichtblau Wolfram Research
