${(x + y + z)}^{3}$

Step 1

Use the Multinomial Theorem.

$x^{3} + 3 x^{2} y + 3 x y^{2} + y^{3} + 3 x^{2} z + 6 x y z + 3 y^{2} z + 3 x z^{2} + 3 y z^{2} + z^{3}$

Step 2.1

Move $3 y^{2} z$ .

$x^{3} + 3 x^{2} y + 3 x y^{2} + y^{3} + 3 x^{2} z + 6 x y z + 3 x z^{2} + 3 y^{2} z + 3 y z^{2} + z^{3}$

Step 2.2

Move $y^{3}$ .

$x^{3} + 3 x^{2} y + 3 x y^{2} + 3 x^{2} z + 6 x y z + 3 x z^{2} + y^{3} + 3 y^{2} z + 3 y z^{2} + z^{3}$

Step 2.3

Move $3 x y^{2}$ .

$x^{3} + 3 x^{2} y + 3 x^{2} z + 3 x y^{2} + 6 x y z + 3 x z^{2} + y^{3} + 3 y^{2} z + 3 y z^{2} + z^{3}$
