^Sorry, haven't read that one yet. I saw the math question and I had to try! The other roots are -2i and -0.579507... I cheated on the second one by using my calculator, but trust me, I've been trying to figure out how to get that last one without it for 20 minutes. Using Descartes' Rule of Signs and synthetic division can only get you so far... =P Yay for ICA class! (Seriously, is there a way to get that fraction without a calculator?? Now I want to know!) |
