- - - - x^2 + bx + (b/2)^2
        =
        (x+b/2)^2
  - - - Discriminant
        
        Do you see b2 − 4ac in the formula above? 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
