Hey friend !!!
1. (a+b)³= a³+b³+3ab(a+b).
OR
(a+b)³= a³+b³+3a²b+3ab².
In the question 2 there is a mistake,
Instead of a³+b³+c³+3abc is a³+b³+c³-3abc.
2. a³+b³+c³-3abc= (a+b+c)(a²+b²+c²-ab-bc-ca).
3. If a+b+c=0, then
a³+b³+c³= 3abc.
4. a³+b³= (a+b)³-3ab(a+b).
OR
a³+b³= (a+b)(a²-ab+b²).
5. a³-b³= (a-b)³+3ab(a-b).
OR
a³-b³= (a-b)(a²+ab+b²).
Hope it's helpful for you:(☺☺☺✌✌✌.
