Does this give you what you want? In[23]:= exprsimpl = 4Factor[(a/4 + b/(4 c))]//Simplify Out[23]= a+(b/c) Richard Hofler -----Original Message----- From: AES [mailto:siegman at stanford.edu] Sent: Monday, November 03, 2008 5:27 AM To: mathgroup at smc.vnet.net Subject: [mg93349] [mg93299] Eliminating common factors? I have a simple, totally algebraic symbolic calculation that displays its output in the form (rewritten here using TeX notation) 4 ( {a \over 4 } + { b \over 4 c } ) where a, b and c are fairly simple products of purely algebraic quantities; \over is the TeX notation for a display fraction; and the curly brackets are just for TeX purposes and are not there in the actual output. Is there any Assumption for Simplify, or any other _simple_ way, to get rid of those (utterly!!!) superfluous 4's? [I suppose the real question is, why doesn't M cancel 'em the hell out in the first place?!?!]
