Question

x (x2 + y2 - z2) + y (-x2 - y2 + z2) – z (x2 + y2 – 22).​

Answer 1

Answer:

$x^3$ + $xy^2 - xz^2 - yx^2 - y^3 + yz^2 - zx^2 - zy^2 + 22z$

Step-by-step explanation:

$x^2$×$x$ = $x^3$

$x$×$y^2$ = $xy^2$

$x$×$(-z^2)$ = $-xz^2$

$y$×$(-x^2)$ = $-yx^2$

$y$×$(-y^2)$ = $-y^3$

$y$×$z^2$ = $yz^2$

$-z$×$x^2$ = $-zx^2$

$-z$×$y^2 = -zy^2$

$-z$×$-22 = 22z$

Answer 2

Answer:

$\sqrt{ \sqrt[5222.22]{?} }$
