Identity:
So we can rewrite the denominator to get
Multiply numerator and denominator by
. Several terms will cancel since
. Also,
. We get
Factorize the numerator, and write
in terms of
in the denominator to factorize it further to get
The
factors cancel, leaving you with
which you could simplify a bit further by writing
