Constructing Complex Roots of Quartics

This example demonstrates how to geometrically construct the complex roots of a quartic equation. Key math concepts include complex numbers, coordinate geometry, and geometric construction. The construction uses GeoGebra commands like Intersect, Line, and Circle, along with objects such as r_1, r_2, a, b, f, A, B, C, L, m, a_1, D, E, O, R, c, d, ComplexRoot, and ConjugateRoot. Suitable for high school and above students to understand the geometric meaning and construction of complex roots.
