     ( a+b+c )²  -  ( a-b-c )²

→   { a² + b² + c² + 2ab + 2bc + 2ac } - { a² + b² + c² + 2a(-b) + 2(-b)(-c) + 2a(-c) }

→  ( a² + b² + c² + 2ab + 2bc + 2ac ) - ( a² + b² + c² -2ab + 2bc - 2ac )

→  a² + b² + c² + 2ab + 2bc + 2ac - a² - b² - c² + 2ab - 2bc + 2ac

→  a² - a² + b² - b² + c² - c² + 2ab  +  2ab + 2bc  - 2bc + 2ac  + 2ac

→  4ab  +  4ac

→ 4a ( b + c ).......Ans
