Math & Algebra Tool

Difference of Two Squares

Instantly factor algebraic expressions following the a² - b² pattern.

Original Expression
(x)² - (5
Factored Result
(x - 5)(x + 5)

Σ The Formula

a² - b² = (a - b)(a + b)

Real World Examples

Standard Numbers
x² - 25 = (x - 5)(x + 5).
Multiple Variables
4k² - 9m² = (2k - 3m)(2k + 3m).

# About This Calculator

The Difference of Two Squares is a specific algebraic pattern where a squared term is subtracted from another squared term. It is one of the most common and useful factoring patterns in algebra.

Identifying this pattern allows you to:

  • Quickly solve quadratic equations.
  • Simplify complex rational expressions.
  • Perform rapid mental math (e.g., 99² - 1² = (99-1)(99+1) = 9,800).

How To Use

  1. Enter the first term **(a)**.
  2. Enter the second term **(b)**.
  3. The tool generates the expression **a² - b²**.
  4. The **Factored Form** is displayed instantly.

Frequently Asked Questions

Does this work for a² + b²?+

No. The sum of two squares cannot be factored using real numbers (it requires complex/imaginary numbers).

What if my coefficient isn't a perfect square?+

You can still use the formula by taking the square root. For example, x² - 2 = (x - √2)(x + √2).
