I know this might seem trivial but I've never had a teacher cover this even though I've had the whole "factor out -1 from numerator " class.(adsbygoogle = window.adsbygoogle || []).push({});

I was thinking of the cases but I haven't found a contradiction to:

[tex]\frac{a}{b-c}=-1\frac{a}{c-b}[/tex]

so is this always true?
