I am trying to integrate a very messy expression using Wolfram online integrator but I get the message:
"You need to use Mathematica to evaluate this expression".
The online integrator works only for relatively simple expressions.
Unfortunately I do not have a license for Mathematica.
Any proposal to overcome this?
Is there a free computer algebra software that can be used as a replacement to Mathematica.
Try the following input on Wolfram|Alpha: Hypergeometric2F1[1, 2, 1, x^2],for example.

This is not my expression.
When I type an expression similar to my expression (A*x*Hypergeometric2F1[1,2,1,x^2]) in Wolfram Alpha I get a very simple answer which cannot be correct.
I checked this by differentiating the answer.
Okay, first of all see here for the definition of the hypergeometric function as a series representation.
Your answer is simple because the case I picked is simple. Here's the derivation:
where is the "Pochhammer symbol."
The summations are simple (I'll show those if you want) giving:
