Lesson plan - Second degree equation

This example demonstrates the graphical representation and properties of quadratic equations. Key math concepts include quadratic functions, discriminant, and the relationship between roots and coefficients. Construction highlights involve LaTeX for text, conditional statements If, Slider animations, and Locus, with objects like a, b, c, x_1, x_2, f, g, Δ. Suitable for high school mathematics teaching or self-study to understand the geometric meaning of quadratic equations.
