The cube of A plus B is either A**3 + B or (A + B)**3 depending on what you intended to be cubed.
a3+b3=(a+b)3-3a2b-3ab2
b + a + b - a = 2b
A+c= 2a+b
pi2
'a' minus 'b' whole cube is equal to 'a cube' minus 'b cube' minus (3 a square b ) plus (3 a b square) . .. .....thanks
The cube of A plus B is either A**3 + B or (A + B)**3 depending on what you intended to be cubed.
(a+b)cube = a cube + b cube + 3a square b + 3ab square
a3+b3=(a+b)3-3a2b-3ab2
This is the formula: (a3)+(b3)=(a+b)(a2-ab+b2)
b + a + b - a = 2b
(a + b)3 = a3 + 3a2b + 3ab2 + b3
It could be a^3 + b or (a + b)^3, depending on the context.
If a = 2b
If you do not assume that "plus" is commutative, all that can be said that it is equal to A plus B.
(a+b)(a+b)Also equal to a2+2ab+b2
A+c= 2a+b
