We’re always considering distance when travel. We are looking for the shortest distance but we are restricted by roads or whatever form of transportation we choose to use.

When we are faced with a quadratic that is not “nice” to factor we need to find a way to factor it. This is where the quadratic formula comes in. The discriminant is a value that can be calculated for each quadratic equation. Depending on the value of the discriminant, we can determine if the quadratic equation has a solution, or has factors, or not.
