Gene,
Yeah I understand that they would need to simplify the radical for the quadratic formula. I taught just simplifying radicals. I did not do any operations. I just told them that like divides like. You can't divide a non radical into a radical. Maybe I should have taught them more but I was more concerned about hitting all the standards and saving any time where possible. I am already into reviewing for the CC regents.
The only mention of a simplifying radicals was in the clarifications. I didn't see any mention of it any where else.
