Factoring Difference of Squares: Practice & Quiz

① This interactive GeoGebra example demonstrates the factorization of the difference of squares (a² - b² = (a+b)(a-b)) through a randomized practice and quiz interface. ② Core math concepts include polynomial factoring, the difference of squares identity, quadratic expressions, and algebraic manipulation. ③ The construction uses GeoGebra commands such as Random, Sequence, RandomElement to generate random coefficients and expressions, Factor to compute the factored form, Textfield and InputBox1/2 for user input, and a button (button1) to trigger checking. Multiple text objects (text1 to text15) display problems, hints, and feedback, creating an interactive learning environment. ④ This resource is suitable for middle school to high school students learning algebra, and for teachers to use in classroom demonstrations or as a self-assessment tool for mastering the difference of squares formula.
