Box Method for Multiplying Binomials - Step-by-Step Visual Guide #3235523 (License: Personal Use)

This image illustrates the box method (also known as the area model) for multiplying two binomials: (2x + 3) and (4x + 5). A 2×2 grid is used where each term from the first binomial multiplies each term from the second, producing 8x², 10x, 12x, and 15; the like terms 10x and 12x are then combined to give the final simplified expression 8x² + 22x + 15. Red diagonal lines indicate the grouping of like terms for addition.
