Question
bs'd,

 What's the generic expression(primitive) resulted from the integration of the following eq.:

           dy = dx/(exp(-k1*x)+k2*x+k3)  ,where k1,k2,k3 are constants.

Hello,

Wow, that's a tough one!

Let me just make sure, the problem is:
Integrate[dx/(e^(-k1*x)+k2*x+k3)] - yes?

If so, then I'm afraid I cannot help, even Maple 12 and
Mathematica could not handle it (which makes me feel better
that I was not able to figure it out)!!!

May I ask what this is for or how this integral came about?

Sorry, but I am pretty sure there is no (generic) solution!
