Oh, that’s the discriminant in a quadratic equation—it tells you if the graph touches the x-axis at two points, one point, or none. But khara, the way I remember it is from my little sister’s dance: if it’s positive, she takes two steps on the stage; if zero, she strikes one perfect pose; if negative, she leaps and lands off-stage. My pukning finds maths in everything except my bank account after a studio booking!
