Discriminant, Roots and Direction of Opening

Today, I created my method for finding the discriminant and roots. It was a simple method of using the equation b^2 - 4ac and testing if it was less than, greater than or equal to zero. This determined if it was one repeated real root, two roots or complex roots. With the a value, I was also able to determine the direction of opening of the parabola based on if the value is negative or positive. This information will be of assistance when they are using my program.
