In regards to the example that I included, can we cancel out the x's? I guess the big question here is how to we identify whether we are dealing with factors or with terms? Answer: When simplifying the rational expression, it is improper to cancel out the x's in general. For instance, (x^2-x)/(x^2+x+1). We cannot cancel x
