1) (a+b)² = a²+2ab+b²
2) (a-b)² = a²-2ab+b²
3) (a+b) (a-b) = a²-b²
4) (x+a) (x+b) = x²+ (a+b)x +ab
5) (a+b+c)² = a²+b²+c²+2ab+2bc+2ca
6) (a-b)³ = a³-b³-3ab(a+b)
7) (a+b)³ = a³+b³+3ab(a+b)
8) a³-b³ = (a-b) (a²+ab+b²)
9) a³+b³ = (a+b) (a²-ab+b²)
10)a³+b³+c³-3abc = (a+b+c)(a²+b²+c²-ab-bc-ca)
Conditional Identity
If a+b+c = 0
Then a³+b³+c³ = 3abc
