It fails because the variables x, y, and z do not appear in the original expression. (It involves only the three variables xy, xz, and yz.) This works, however: Factor[x y - x z + y^2 - y z] (x + y) (y - z) Bobby On Thu, 30 Dec 2010 03:09:17 -0600, r_poetic <radford.schantz at mms.gov> wrote: > Hello, > an easy question: > > why does Factor[xy-xz+y^2-yz] fail to return (x+y)(y-z), and what > command would do that? > > Thanks! > > -- DrMajorBob at yahoo.com
