plz it's important right now ​

Answer 1

Answer:

Step-by-step explanation:

{ (a + b) + c }³

= (a + b )³ + c³ + 3 (a + b )² c + 3 (a + b ) c²

= a³ + b³ + 3a²b + 3ab² + c³ + 3c ( a² + 2ab + b² ) + 3c² ( a + b)

= a³ + b³ + 3a²b + 3ab² + c³ + 3a²c + 6abc + 3b²c + 3ac² + 3bc²

= a³ + b³ + c³ + 3a²b + 3ab² + 3b²c + 3bc² + 3a²c + 3ac² + 6abc
