The discriminant is a quick way to determine the quantity and type of the possible solutions of a quadratic equation. if the discriminant has a value of 28, what can we conclude about the solution(s) to the equation?

A positive discriminant means that there are two real solutions.
A negative discriminant means there are two complex solutions.
A discriminant equal to zero means there is one real solution.

Wow I hate it when we have these types of questions, like when is my boss or when am I ever gon use this in life. The equation uses Pythagorean’s theorem and when you get the end of the boys shadow touching the floor it is the vertical angle for the trees shadow, then you just reverse engineer the problem... someone else will do it
