McDougal Littell Algebra 

I got copies of textbooks for the classes which I'll be teaching later in November. For the 4-semester Algebra 1 course, they use McDougal Littell's Algebra text, and looking over the book, I find it a bit disturbing that they give the quadratic formula before they even do polynomial multiplication, let alone factoring. The end result is that the quadratic formula ends up seeming like it comes out of nowhere.

On the other hand, they defer talking about percentages until they deal with ratios, direct variance and rational expressions, which has some benefits, I think.
