This example dynamically illustrates the complex roots of a quadratic equation through geometric visualization. It involves core math concepts like complex numbers, quadratic roots, angles, and symmetry. GeoGebra commands used include Root, ComplexRoot, Mirror, Intersect, and Circle to plot root trajectories, mirror transformations, and intersection points. Suitable for high school mathematics education to understand the distribution and properties of complex roots.

GeoGebra Commands & Parameters

  1. Root(f) → A, B
  2. ComplexRoot(f) → z_1, z_2
  3. Mirror(f, C) → f_1
  4. Intersect(f_1, xAxis) → D, E
  5. Circle((D + E) / 2, D) → d
