Answer 2

Step-by-step explanation:

$(\frac{1}{2} x^{2} +\frac{1}{2} y^{2}+\frac{1}{2} z^{2})- (\frac{1}{2}+\frac{3}{2} x^{2}+\frac{5}{2} y^{2} +\frac{7}{2} z^{2})$

$\frac{1}{2} x^{2} +\frac{1}{2} y^{2}+\frac{1}{2} z^{2} - \frac{1}{2}-\frac{3}{2} x^{2}-\frac{5}{2} y^{2} -\frac{7}{2} z^{2}$

$\frac{1}{2} x^{2} -\frac{3}{2} x^{2}+\frac{1}{2} y^{2}-\frac{5}{2} y^{2}+\frac{1}{2} z^{2} -\frac{7}{2} z^{2}- \frac{1}{2}$

$\frac{1-3}{2} x^{2}+\frac{1-5}{2} y^{2}+\frac{1-7}{2} z^{2} - \frac{1}{2}$

$\frac{-2}{2} x^{2}+\frac{(-4)}{2} y^{2}+\frac{(-6)}{2} z^{2} - \frac{1}{2}$

$-x^{2}-2 y^{2}-3z^{2} - \frac{1}{2}$
