Wzory Skróconego Mnożenia: Essential Algebraic Formulas

This page presents a comprehensive overview of wzory skróconego mnożenia (shortened multiplication formulas), which are fundamental in algebra and higher mathematics. These formulas are particularly important for students in 1 liceum as they form the basis for more advanced mathematical concepts.

The page begins by listing the core formulas:

1. $a + b$² = a² + 2ab + b² (Square of sum)
2. $a - b$² = a² - 2ab + b² (Square of difference)
3. a² - b² = $a - b$$a + b$ (Difference of squares)
4. $a + b$³ = a³ + 3a²b + 3ab² + b³ (Cube of sum)
5. $a - b$³ = a³ - 3a²b + 3ab² - b³ (Cube of difference)
6. a³ - b³ = $a - b$$a² + ab + b²$ (Difference of cubes)
