whenever i see that integrating factor for solving a linear differential equation with(adsbygoogle = window.adsbygoogle || []).push({});

e^{int. p(x) dx}and then multiplied out in the equation, there seems to be no constant. i tried solving an equation with it the other day, and got an incorrect solution because of it (i think. at least i got a correct solution when i neglected it).

why is this?
