Factoring Difference of Squares with Algebra Tiles

The video tutorial explores the process of factoring the difference of squares using algebra tiles. It begins by setting up the problem with an x squared tile and four unit tiles representing negative four. The tutorial demonstrates how to complete the rectangle by adding and subtracting X tiles, ultimately factoring the expression x squared minus 4 into (X + 2)(X - 2). The video concludes with a recap of the technique, emphasizing the use of algebra tiles for visualizing and solving factoring problems.
