(a+b) ^2 = a^2+b^2+2ab
(a-b)^2= a^2+ b^2 - 2ab
(a+b) (a-b) = a^2 - b^2
(a + b + c)^2 = a^2 + b^2 + c^2 + 2ab + 2bc + 2ca
(a - b - c)^2 = a^2 + b^2 + c^2 – 2ab + 2bc – 2ca
(a - b)^3 = a^3 - b^3 - 3ab (a - b)
(a + b)^3 = a^3 +b^3 +3ab (a + b)
(a + b + c)³ = a³+ b³+ c³+3(a+b) (b +c) (a+c)
ETC.....
These r the some identities.
