Math Help - The Quotient Rule

1. The Quotient Rule

I have a question about the quotient rule

Today my teacher taught us the quotient rule and she labeled it:
$(u/v) prime = uprimev-uvprime/ v^2$

While in the book it states
$(u/v) prime = uvprime - vuprime/ v^2$

Is there a difference?

Of course there is. One is the negative of the other!

$\left( \frac{u}{v} \right)^{'} = \frac{u' v - v' u}{v^2}$.

$\left( \frac{u}{v} \right)^{'} \neq \frac{u v' - v u'}{v^2}$.
