Comment #25 on issue 2624 by [email protected]: Sympy 0.7.1 can't integrate
Gaussians

Somehow this seems to have been lost:
Thanks for the tip. Factor_terms has the unfortunate effect of turning
things like a/2 + 1 into (a+2)/2 - first off I don't actually find this
simpler, but moreover how do you even enter (a+2)/2 without it
autoexpanding to a/2 + 1?

factor_terms was written for such purposes as this; to give a
non-destructive simplification of exressions. In fact, it works in this
case:
factor_terms(integrate(exp(-x**2 + 2*x - 1), (x, -oo, oo)))
sqrt(pi)
I would suggest using that at the end of the integrate routine.
