All That Matters in Math Algebraic Identities (Sandeep Srivastava)

This booklet contains the following concept(s).

Algebraic Identities
Identity : (a + b) (a – b) = a² – b²
Identity : (a + b)² = a² + 2ab + b²
Identity : (a – b)² = a² – 2ab + b²
Identity : a³ + b³ = (a + b)³ – 3ab (a + b)
Identity : a³ – b³ = (a – b)³ + 3ab (a – b)
Identity : (a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ca
Identity : a³ + b³ + c³ – 3abc = (a + b + c) (a² + b² + c² – ab – bc – ca)
