If you solved this problem correctly, your session withÌýMathematicaÌýshould have gone something like this:

DSolve[(2x y[x]+3)+(x^2 -1) y'[x]==0, y[x], x]

If you didn't get the above solution to the differential equation, you might want to go back toÌýMathematicaÌýand check your work. (Or you could simply claim thatÌýyouÌýare correct, and thatÌýmyÌýsolution is wrong!) A common mistake is to forget to put either a [SPACE] or a * between theÌýxÌýand theÌýyÌýin the command. (If you don't do this,ÌýMathematicaÌýthinks that you have aÌýsingleÌývariable here calledÌýxy.)
