Comment:
Indeed, many thanks. With this easy patch the output is now
{{{
sage: sage: x=function('x',t)
sage: sage: var('c')
c
sage: sage: desolve(diff(x,t)+2*x==t^2-2*t+c,x,ivar=t).expand()
1/2*t^2 + _C*e^(-2*t) + 1/2*c - 3/2*t + 3/4
sage: desolve(diff(f(x),x,x)-f(x),f(x))
_K2*e^(-x) + _K1*e^x
}}}
Any more variables?
