Question

please answer me fast ​

Answer 1

Answer:

Using formula (a+b)^3 and (a-b)^3

=(a^3 + b^3 +3a^2b +3ab^2 ) (a^3 + b^3- 3a^2b -3ab^2)

=2a^3 + 2b^3 +3a^2b -3a^2b + 3ab^2 -3ab^2 ( Since 3a^2b and -3a^2b are opposite signs they got cancelled same is the case for 3ab^2-3ab^2)

So finally we get our answer ^_^

2a^3 +2b^3

=2 (a^3 +b^3)

Hope it helps uh a lot ❤
