René Descartes started with "I think, therefore I am." While quite short, that is a complete sentence.
The values of 
that make the equation a true statement are the -coordinates of the points where the graph of the analogous quadratic function intersect the -axis, if any exist. In this case, since the signs on the lead coefficient and the constant term are opposite, you are guaranteed that the graph of the function will intersect the -axis in two distinct points, and therefore the equation will have two distinct real roots.
