Answer 2

HEY MATE HERE IS YOUR ANSWER

QUESTION :-

${x}^{3} + {y}^{3} = (x + y)( {x}^{2} - xy + {y}^{2} )$
Now,

$x( {x}^{2} - xy + {y}^{2} ) + y( {x}^{2} - xy + {y}^{2})$

${x}^{3} - {x}^{2}y + x {y}^{2} +y {x}^{2} - x {y}^{2} + {y}^{3}$
Note : (-) and (+) will be cutted if the same

So,

Remain

X^3 + y^3

HENCE, It is verified that

$= > \: {x}^{3} + {y}^{3}$
