Squaring a Binomial Visually

This animation breaks down (x + 3)² by showing why the expression is not simply x² + 9. Using an area model, a square is divided into four regions representing x², 3x, 3x, and 9, visually proving the expansion x² + 6x + 9. Designed for ASVAB prep students, it reinforces the FOIL method and the binomial square pattern through geometric intuition rather than rote memorization.
