Solving x² = 121: Algebraic Steps and Factoring Method #2258995 (License: Personal Use)

The image displays three sequential algebraic steps: starting with x² = 121, subtracting 121 from both sides to yield x² - 121 = 121 - 121, and simplifying to x² - 121 = 0. This transformation is foundational for solving using difference of squares (x - 11)(x + 11) = 0, revealing solutions x = ±11.
