Algebraic Identity (a + b)² Explained Visually | Geometric Proof #29477 (License: Personal Use)

The image illustrates the algebraic identity (a + b)² by partitioning a square of side length (a + b) into four regions: a red square of area a², a blue square of area b², and two black rectangles each of area ab. The total area is summed as a² + ab + ab + b², simplifying to a² + 2ab + b², confirming the expansion of the binomial square.
