ALGEBRA
1) ( A+B )2 = A2 + B2 + 2AB
2) ( A-B )2 = A2 + B2 - 2AB
3) ( A2 – B2 ) = ( A+B ). ( A-B )
4) A3 + B3 = ( A+B ).(A2 + B2 – AB ) ,(A + B)3 - 3AB( A + B)
5) A3 - B3 = ( A - B ).(A2 + B2+ AB ) , (A - B)3+ 3AB( A – B )
6) (A + B)3 = A3 + B3+ 3AB(A + B)
7) (A - B)3 = A3 - B3 - 3AB(A - B)
8) ( A-B )2 = ( A+B )2 - 4AB
9) ( A+B )2 = ( A-B )2 + 4AB
Am. An = (A)m+n
An = 1/A-n
A-n = 1/An
(Am)n = Amn = (An)m
A0 = 1
A1/2 = Root A
Am/An = A(m-n)
