68Understanding The Algebraic Identities
Class - 6th to 10 th standard
(a + b)² = a² + 2ab + b²
(a - b)² = a² - 2ab + b²
a² + b² = (a + b)² - 2ab
a² - b² = (a - b)(a + b)
(a + b)³ = a³ + 3a²b + 3ab² + b³
(a - b)³ = a³-3a²b + 3ab²-b³
a³ - b³ = (a - b)(a² + ab + b²)
a³ + b³ = (a + b)(a² - ab + b²)
(a + b + c)² = a² + b² + c² + 2ab + 2bc +2ca
(a - b-c)² = a² + b² + c² - 2ab + 2bc - 2ca
