For example, I have:

CharacteristicPolynomial[m, x]
0.5 + 0.1 x + x^2

gives errors.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Plot has HoldAll attribute so you need to Evaluate it first or add the option , Evaluated -> True. –  Kuba Nov 15 '13 at 9:34
I think it should be marked as a duplicate of Evaluate or not or expression evaluation in Plot. –  Kuba Nov 15 '13 at 9:43
