(a+b)² = a²+b²+2ab
a²-b² = (a+b)(a-b)
(a+b)³ = a³+b³+3ab(a+b)
(a+b+c)² = a²+b²+c²+2ab + 2bc + 2ca
if a+b+c = 0, then a³+b³+c³= 3
(a+b)²+(a-b)² = 2 ( a²+b²)
(a+b)²-(a-b)²= 4ab
a²-b² = (a+b)(a-b)
(a+b)³ = a³+b³+3ab(a+b)
(a+b+c)² = a²+b²+c²+2ab + 2bc + 2ca
if a+b+c = 0, then a³+b³+c³= 3
(a+b)²+(a-b)² = 2 ( a²+b²)
(a+b)²-(a-b)²= 4ab
