Question

please tell all the identities of aplha and beta...like alpha beta whole square .... alpha squate plus beta square ....plz tell all identities

Answer 1

here I take alpha=a and beta=b
(a+b)^2=a^+b^+2ab
(a-b)^2=a^-2ab+b^2
a^-b^2=(a-b)(a+b)

Answer 2

Hey mate I think this may help you out!!

1)(a+b)^2= a^2+b^2+2ab.
2)(a-b)^2=a^2+b^2-2ab.
3)(a^2-b^2)=(a+b)(a-b).
4)(a+b)^3=a^3+b^3+3ab(a+b).
