    Here's the quadratic equation formula:

    Y = ax^2 + bx + c

    A = 1

    B = - 4

    C = 5

    Discriminant: - 4^2 - (4*1*5) = - 4

    If discriminant is negative - > No real solutions

    If discriminant is zero - > One real solution

    If discriminant is positive - -> two real solutions
