I'm opening this one now.
When running the following code, one obtains a wrong output:
y=function('y')(x)
desolve(diff(y)==4*y/x+x*sqrt(y),y,ics=[1,1]).factor()
The output is `1/4*x^4*(log(x) - 2)^2` instead of `1/4*x^4*(log(x) + 2)^2`. Mathematica however outputs both (by running `DSolve[{D[y[x], x] == 4*y[x]/x + x*Sqrt[y[x]], y[1] == 1}, y[x], x]`).ThrashMon, 14 Jan 2019 10:54:14 -0600http://ask.sagemath.org/question/45046/
