The discriminant is:
The general equation for a quadratic has the form:
---------------------
The discriminant is real and positive, and it is not zero
also, the discriminant is a perfect square. When you
plug the discriminant back into the quadratic
formula, you have 2 real, rational roots
---------------------
Here's the plot of the equation:
