  1. Hi there. Maybe rational number is a better word that a fraction. I was expecting my students to find numbers so that at least one solution was rational but some students created a quadratic so that, for example, (7+ sqrt3)/4 was one solution. Technically it is a fraction but not what I was expecting.
