Answer 2

$\bigstar$ Question:

If $x+y+z=0,$ show that $x^{3} + y^{3} + z^{3} = 3xyz$

$\bigstar$ Solution:

We know that,

$x^{3} + y^{3} + z^{3} = 3xyz$

$\implies (x+y+z)(x^{2} + y^{2} + z^{2} - xy- yz = xz)$

Now, according to the question,

Let, $(x+y+z)=0$

Then,

$x^{3} + y^{3} + z^{3} = 3xyz = (0)(x^{2} + y^{2} + z^{2} -xy-yz-xz)$

$\implies x^{3} + y^{3} + z^{3} -3xyz= 0$

$\implies \boxed{\underline{\underline{x^{3} + y^{3} + z^{2} = 3xyz }}}$

Hence, proved!
