Visual Proof of (a-b)² Algebraic Identity - Geometry & Algebra #29466 (License: Personal Use)

This diagram visually demonstrates the expansion of (a-b)² by dissecting a square of side length a into smaller regions, including a central square of side (a-b), two rectangles of area ab, and a small square of side b. Dashed lines indicate auxiliary constructions used to isolate the (a-b)² region and verify the identity through area subtraction. The labeling of α and β (representing a and b) reinforces the algebraic-geometric correspondence.

Used in math education resources, algebra textbooks, or online tutorials explaining binomial expansions via geometric reasoning; targets students learning algebraic identities and teachers preparing visual aids.
