Try the following instead: In[1]:= m={{.3,.7},{.4,.6}}; i=IdentityMatrix[2]; j={{1},{1}}; inv=Inverse[lambda i - m]; Map[Factor,t,3]//.(1.x_->x) Remember that "Factor[poly] factors a polynomial over the integers", and your inv is not a polynomial.

The problem can be replicated as follows: m={{.3,.7},{.4,.6}} i=IdentityMatrix[2] j={{1},{1}} inv=Inverse[lambda i - m] Cancel[Factor[inv.j]] The last command should cancel the common factors, but it does not! Any help on that. Thank you. John. -------------------------------------------------------------------- Mail2Web - Check your email from the web at http://www.mail2web.com/ .
