In this video, we explore factorization using algebra tiles to make algebra more visual and intuitive. Beginning with rectangles, equations are represented geometrically to build a strong foundation. We then demonstrate expansion using algebraic tiles, showing how multiplication unfolds step by step. The lesson continues by visualizing and solving equations when đť‘Ą has a coefficient, helping learners see how scaling impacts solutions. Finally, we generalize the rectangle method, turning it into a powerful tool for factorization and connecting algebra with geometry in a clear, engaging way.
