Algebra Tiles Operations and Concepts

Mrs. A introduces algebra tiles as a tool for factoring quadratic expressions. She demonstrates the process with two examples: x^2 - 3x + 2 and x^2 - x - 2. The video explains how to arrange tiles to form a complete rectangle, representing the area model of the expression. By examining the length and width of the rectangle, the factored form of the quadratic is determined. The video emphasizes the importance of understanding the relationship between the area model and the algebraic expression.
