Expanded Form and Quadratic Formula Demo

This example demonstrates the application of the expanded form and quadratic formula in coordinate geometry for quadratic functions. Key math concepts include quadratic functions, root formulas, derivatives, and optimization problems. GeoGebra commands used are Intersect and Vertex, with objects like c, b, a, d, x_1, x_2, etc. Suitable for high school students learning functions, derivatives, and optimization problems.
