Trouble with this differential equation

[matteo86bo]

Hi!
can you help me to solve this differential equation?

$$<br /> (x+1)f^{\prime}(x)-xf(x)+c=0<br />$$

c is a constant

Rewrite the equation as y' - x/(x + 1) = -c/(x + 1) and find an integrating factor. Your text should have some examples of this technique.

BTW, this is NOT a precalculus question.
