Whatisthe problem ? Anyway, to factorize such equations, you have some methods :

- identity (before any of the following methods, check if your quadratic is not an identity)

- guestimate (try a factorization, expand and check)

- solve & factorize (solve the quadratic by the quadratic formula, and you can easily factorize - yeah I know that perhaps you might be factorizing to solve )

- brainkiller (the most efficient method once you get the grip, quick and easy (see next post ofMattio))
