If we're asked to expand an irrational partial fraction, we need to rationalize it first, right? I've forgotten (well not totally) how to perform polynomial division. Here are a few examples: 1. (1000x +1000000)/(.4x + 200). For this one I got 50000. 2. (500x + 60000)/(x+100). For this one I got 600, is that right? It doesn't feel like I'm doing them correctly, if my answers are wrong can somebody walk me through them?
