    Quadratic formula
    The equation has solution(s) given by the quadratic formula:

    Assuming a, b and c are all real numbers, this splits into 3 cases.

    Case 1:
    In this case, since , the "two" solutions are in fact a single solution,

    Case 2:
    In this case, there are two different, real number ...
