Visualization of Imaginary Roots of a Quadratic

This shows a visual interpretation of imaginary roots of a quadratic. The x coordinate of the vertex +- the coefficient of the imaginary part of the solution is equal to the red parabola's intercepts. NOTE: The x-axis should be an complex plane and the parabola would be rotated 90 degrees to have these imaginary "intercepts" intersect the plane in the correct location.
