can u tell me other,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,algebric..............................formula........................................not like[a+b]2..............beside it////////////////////////////////////////

Answer 11

Bring \(3ab(a+b)\), on the left side by subtracting it from both the sides:

\[(a+b)^3 - 3ab(a+b) = a^3 + b^3\]

Answer 12

There are many.. :P

Answer 13

tell me one by one

Answer 14

\[a^3 + b^3 = (a+b)[(a+b)^2 - 3ab] \implies a^3 + b^3 = (a+b)[a^2 + b^2 + 2ab - 3ab] \\ a^3 + b^3 = (a+b)[a^2 +b^2 - ab]\]

Answer 15

Okay.
First one : \((a+b+c)^2 = ??\)

Answer 16

tell

Answer 17

\[(a+b+c)^2 = a^2 + b^2 + c^2 + 2ab + 2bc + 2ca\]
