Polynomial Subtraction Demo

This example demonstrates the calculation and visualization process of polynomial subtraction. It involves core math concepts like polynomial operations, combining like terms, and analytical geometry representation. The construction utilizes GeoGebra commands Random and Simplify, along with objects such as a_1 to b_3, f, g, f_1, g_1, button1 to button2, text2, showans, and text3. It is suitable for high school mathematics education, helping students understand the algorithm and geometric meaning of polynomial subtraction.
