stuff about polynomials
So, I think of the following things as being standard high-school fare:
1. Synthetic division
2. Finding all the rational roots of a polynomial with integer coefficients by factoring its leading and trailing terms.
Ariel doesn't.
Which one of us do you guys think is right?
Complicating factors include:
a) There was one year of math that I learned out of a textbook. So if it was covered in that book, I probably learned it whether or not I was really supposed to (unless I thought it was hard at the time -- I seem to recall getting stuck on its explanation of matrix multiplication, for example) and mentally filed it under "stuff people learn in that class".
b) Ariel's high school algebra was kind of spotty, so she might not have learned it even if it was standard.
