Study Notes
Algebraic Identities
- (a + b)² = a² + 2ab + b²: This identity represents the square of a binomial sum.
- (a - b)² = a² - 2ab + b²: This identity represents the square of a binomial difference.
- a² - b² = (a - b)(a + b): This identity shows the difference of two squares.
- a³ - b³ = (a - b)(a² + ab + b²): This identity represents the difference of two cubes.
- a³ + b³ = (a + b)(a² - ab + b²): This identity represents the sum of two cubes.
- (a + b)³ = a³ + 3a²b + 3ab² + b³: This represents the cube of a binomial sum.
- (a - b)³ = a³ - 3a²b + 3ab² - b³: This represents the cube of a binomial difference.
