Add in a question where they factor a quadratic where
My students did not remember how to factor for Activity 1.5.6. They mostly did guess and check to narrow down to the right answer for part (a). Which is fine here, I guess. So maybe add factoring when a isn't 1 to the RAT. Or switch this one so that a=1. Then they can practice the idea without factoring holding them back as much. Activity 1.5.7(c) also gave them trouble. We talked about how to factor it, but usually I would say that if they don't see how to factor it fairly quickly to just use quadratic formula. But we weren't there yet.
