How can I find a solution of the following differential equation: $$\frac{d^2y}{dx^2} =\exp(x^2+ x)$$

Thanks!

    Alpha obtains an [answer](http://www.wolframalpha.com/input/?i=solve%20y%28x%29%27%27-exp%28x%5E2%2bx%29=0) in term of (imaginary) error function (this means that the primitive of the primitive of $e^{x^2+x}$ is not much more complicated than the primitive itself and that no elementary solution exists).2012-12-20

    You can also integrate the Taylor series termwise.2012-12-20
