Factoring Polynomials with Algebra Tiles

Anil Kumar demonstrates how to factor the difference of squares using algebra tiles. The video explains the process of setting up the problem with 4x^2 - 1, arranging algebra tiles to represent the terms, and completing the rectangle by adding and subtracting x tiles. The dimensions of the completed rectangle reveal the factors of the expression, which are 2x + 1 and 2x - 1. This technique provides a visual method for understanding polynomial factoring.
