This now gives
h[3] integrate(x**2 * exp(x) * cos(x), x)
exp(x)*sin(x)/2 + x**2*exp(x)*sin(x)/2 - x*exp(x)*sin(x) -

We should rewrite simplify() with factor() and other recently improved
function. However, before we do this, we should have good expression

If you are just pulling out a visible term (not a hidden factor) then
consider using
terms_gcd:
terms_gcd(ans)
(-cos(x) + x**2*cos(x) +

This is fixed in the new polys, but it needs to be tested:
In [1]: e = integrate(x**2 * exp(x) * cos(x), x)
In [2]: e
Out[2]:
x 2 x
