Quadratic equations are actually used in everyday life, as when calculating areas, determining a product's profit or formulating the speed of an object.
Step-by-step explanation:
It is called the Discriminant, because it can "discriminate" between the possible types of answer: when b2 − 4ac is positive, we get two Real solutions. when it is zero we get just ONE real solution (both answers are the same) when it is negative we get a pair of Complex solutions.
