Where Are the Quadratic's Complex Roots?
Páll-Szabó, Ágnes Orsolya
Acta Didactica Napocensia, v8 n1 p37-47 2015
A picture is worth more than a thousand words--in mathematics too. Many students fail in learning mathematics because, in some cases, teachers do not offer the necessary visualization. Nowadays technology overcomes this problem: computer aided instruction is one of the most efficients methods in teaching mathematics. In this article we try to discuss some methods of visualizing complex roots, with examples. The first method presented is the auxiliary polynomial method, followed by the the tangent line method. One of the most interesting but less known method is Lill's circle. Another method discussed in the article is Domain Coloring via the Color Wheel.
