A + b whole cube plus a minus b whole cube is equal to

TeraDost: a plus b whole cube minus a minus b whole cube i.e. ( a + b )³ - ( a - b )³

(a + b)³ = a³ + b³ + 3a²b + 3ab²

(a - b)³ = a³ - b³ - 3a²b + 3ab²

( a + b )³ - ( a - b )³ = a³ + b³ + 3a²b + 3ab² - (a³ - b³ - 3a²b + 3ab²)

( a + b )³ - ( a - b )³ = a³ - a³ + b³ + b³ + 3a²b + 3a²b + 3ab² - 3ab²

( a + b )³ - ( a - b )³ = 2b³ + 6a²b or 2b(3a² + b²)
