Today we continued working with adding and subtracting rational expressions. We reviewed factoring types GCF, trinomial, difference of squares, and grouping. We used these techniques to simplify. JPaul knows what to do, but his factoring skills could be improved. We will continue to see factoring throughout this Chapter, so we pulled difficult factoring problems from the internet and I had JPaul work them out, one by one. This was a good review for him.
