( a + b )2 = a2 + 2ab + b2
( a - b )2 = a2 - 2ab + b2
( a + b + c )2 = a2 + b2 + c2 + 2ab + 2bc + 2 ca
( a + b )3 = a3 + b3 + 3ab ( a + b )
( a - b )3 = a3 - b3 - 3ab ( a - b )
( a - b )2 = a2 - 2ab + b2
( a + b + c )2 = a2 + b2 + c2 + 2ab + 2bc + 2 ca
( a + b )3 = a3 + b3 + 3ab ( a + b )
( a - b )3 = a3 - b3 - 3ab ( a - b )
