Ah, I'm starting to get a glimmer of understanding. Thanks guys!

See, I get confused when I see things like this from some college website I can't link to because I don't have enough posts yet. This means if there is a real solution for R=0, then I can't just simplify it away? So if the function was F(x)=[(X+1)(X^2+1)]/(X^2+1), I could factor out the...

I understand why the left hand side is undefined, I just don't get why it can't be reduced to the lowest terms in the first place.

Thanks! I think the part I'm getting stuck on is why [(x+1)(x-4)]/(x-4)≠(x+1)

Say we have a rational function P(x)=(x^2-3x-4)/(x-4)=[(x+1)(x-4)]/(x-4) I'm a little confused as to why the (x-4) doesn't cancel out. It graphs the same as y=x+1 for x≠4. I feel like I'm missing something from the order of operations.
