3.9, due on October 15

1. I don't understand why they picked 3 and 4 in the proposition. Is that just one pair of numbers that will work? Also, it took me a minute to understand how they got the solutions + or - 15 and + or - 29, but I got it.

2. This was exciting because I can see how it might apply to RSA. Also that very last statement in italics, saying how finding the square roots is computationally equivalent to factoring, was nice.
