Seriously. I. hate. math. I seriously doubt I'm ever going to need to know the Rational Root Theorem for ANYTHING, EVER. How about I use the Rational Root theorem to prove my teacher is a dickhead? I'll do that! In fact, I'll devote my whole life to proving it. Oh, wait, I don't need to! It's completely self-evident that he IS a dickhead! Try using that synthetic division to divide your head from your ass, sir! Take those stupid logarithms and shove em. Thankyouverymuch.
