does integral of exp(-a*x^4-b*x^2-c*x) have decision in indefinite limits?

Sorry - not Mathematica as program but Mathematic as science.

But you can use numerical Math:

And by using WolframAlpha (http://www.wolframalpha.com/input/?i=integrate+exp%28-a*x%5E4-b*x%5E2-c*x%29+dx😞

We can get the same result in Mathcad.

Ok.

to ViktorKorobov : is it a general decision? Is value integral for +indefinite indefinite?
