 ...we can write the term  as   



so,

  ....both terms have  in common, so we can factor out 



.... write the term  as  and  as  



....now we have difference of squares, factor it  



....one more time we have difference of squares, factor it 













....group first two terms together and second two terms together



 ...from a group of first two terms factor out , from a second group factor out
