4.2

1. What was the most difficult part of the reading for you?
Tonight, I got nervous for doing the homework for this section. Nothing really stood out to me as particularly difficult, but realizing that we're probably going to have to use the division algorithm a couple of times to find the gcd for two polynomials worried me. I have a hard enough time dividing polynomials cleanly on my paper so that I can follow it, so having to do it several times makes me a tad nervous, but I guess we just take it one problem at a time.

2. A caution for the future:
Something that worries me, mostly because I know how forgetful I am, will be to convert polynomials to "monics" when calling them the gcd. Hopefully by talking about it in this tiny paragraph will remind me to make sure that the leading coefficient is 1 when talking about it.... I think I can.... But man, I bet finding the formulas (like, the reverse of the division algorithm) is going to suck....
