<PRE><B>Question 193706</B>
Please  review  our  interpretation  of  the  problem  carefully,,to  be  sure  we  solved  your  problem
,
we  are  going  to  factor  all  trinomials,
and  then  revise  form  from,,(a/b)/(c*d),,,to,  (a/b)*(d/c),   where  d=1
and  then  simplify
,
this  gives  us
,
((4a-1)(a-1)/(2a-1)(3a-2) )*(1/( (a-1)(a+2)(2a-1)(a+2)))
,
canceling  (a-1)  in  num  and  den,,,and  simplying,,
,
(4a-1) / (  (2a-1)^2  * (a+2)^2 * (3a-2)  )

please  double  check,,,thanks</PRE>
