Answer 2

Answer:

NOOO

Step-by-step explanation:

( a + b )³ = a³ + b³ + 3 ab ( a + b )

RIGHT

a³ + b³ = ( a + b )( a² - ab + b² )

a³ - b³ = ( a - b )( a² + ab + b² )

a + b + c = 0 then a³ + b³ + c³ = 3 abc

( a + b )² = a² + b² + 2 ab

( a - b )² = a² + b² - 2 ab

( a + b + c )² = a² + b² + c² + 2( ab + bc + ac )

( a + b )² - ( a - b )² = 4 ab

( a + b )² + ( a - b )² = 2 a² + 2 b²

Hope it helps ;)
