Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

This is not strictly a DE question, but I came across this while working on one. This isn't the first time I got this and I just can't remember this from my 1st year maths. Some knowledge would be greatly appreciated. In the answer they do the following:

[itex](\frac{1}{x})(\frac{dy}{dx}) - (\frac{1}{x^2})y \Rightarrow

(\frac{d}{dx})[(\frac{1}{x})y][/itex]

Now I want to know how? I just cant simplify it. Silly question, but need the help!

Thanks
