\(=> a^3 + b^3 = (a+b)^3 – 3ab (a+b)\) [Note Take comman part (a+b)] \(=> a^3 + b^3 = (a+b) ((a+b)^2 – 3ab) \) we know that formula of \( (a+b)^2 =a^2+ b^2 + 2ab \) \(=> a^3 + b^3 = (a+b) (a^2+ b^2 + 2ab – 3ab) \) \(=> a^3 + b^3 = (a+b) (a^2+ b^2 – ab) \) Proof Formula \(=> a^3 + b^3 = (a+b) (a^2+ b^2 – ab) \).
a 3 b 3 c 3 3abc formula Formula for a^3 + b^3 + c^3
a³ + b³ = (a + b) (a² – ab + b²) And their is also an easy derivation of the given expression It is given below you know that (a + b)³ = a³ + 3ab (a + b) + b³ then a³ + b³ = (a + b)³ – 3ab (a + b) = (a + b) [ (a + b)² – 3ab] = (a + b) (a² + 2ab + b² – 3ab) = (a + b) (a² – ab + b² ) I hope this is helpful for you all ) CHEERS ! 367K views.
