Main Question or Discussion Point

Hello there!
I'm trying to read a set of notes on the standard model and the author states the following equality without any explanation:
[tex]-u^{-1}(\partial_\mu u)u^{-1} = \partial_\mu(u^{-1}), [/tex]
u is here a NxN representation of some continuous gauge group and is a function over spacetime.
Does this equality hold and in that case why?

Thanks!
