Geometrical Solutions of Quadratic Equations.
Grewal, A. S.; Godloza, L.
International Journal of Mathematical Education in Science and Technology, v30 n4 p573-79 Jul-Aug 1999
Demonstrates that the equation of a circle (x-h)2 + (y-k)2 = r2 with center (h; k) and radius r reduces to a quadratic equation x2-2xh + (h2 + k2 -r2) = O at the intersection with the x-axis. Illustrates how to determine the center of a circle as well as a point on a circle. (Author/ASK)
