Step 1.1

Add

- 8

$- 8$ and

4

$4$ .

- 5 y - 2 z + \sqrt{\frac{1}{2} (x - 4)} - 2 = 3^{2} (\frac{1}{6}) + 3 x^{2} + 2 x - 5 y - 2 z

$- 5 y - 2 z + \sqrt{\frac{1}{2} (x - 4)} - 2 = 3^{2} (\frac{1}{6}) + 3 x^{2} + 2 x - 5 y - 2 z$

Step 1.2

Reorder factors in

- 5 y - 2 z + \sqrt{\frac{1}{2} (x - 4)} - 2

$- 5 y - 2 z + \sqrt{\frac{1}{2} (x - 4)} - 2$ .

- 5 y - 2 z + \sqrt{(x - 4) \frac{1}{2}} - 2 = 3^{2} (\frac{1}{6}) + 3 x^{2} + 2 x - 5 y - 2 z

$- 5 y - 2 z + \sqrt{(x - 4) \frac{1}{2}} - 2 = 3^{2} (\frac{1}{6}) + 3 x^{2} + 2 x - 5 y - 2 z$

Step 1.3.1

Raise

3

$3$ to the power of

2

$2$ .

- 5 y - 2 z + \sqrt{(x - 4) \frac{1}{2}} - 2 = 9 (\frac{1}{6}) + 3 x^{2} + 2 x - 5 y - 2 z

$- 5 y - 2 z + \sqrt{(x - 4) \frac{1}{2}} - 2 = 9 (\frac{1}{6}) + 3 x^{2} + 2 x - 5 y - 2 z$

Step 1.3.2.1

Factor

3

$3$ out of

9

$9$ .

- 5 y - 2 z + \sqrt{(x - 4) \frac{1}{2}} - 2 = 3 (3) \frac{1}{6} + 3 x^{2} + 2 x - 5 y - 2 z

$- 5 y - 2 z + \sqrt{(x - 4) \frac{1}{2}} - 2 = 3 (3) \frac{1}{6} + 3 x^{2} + 2 x - 5 y - 2 z$

Step 1.3.2.2

Factor

3

$3$ out of

6

$6$ .

- 5 y - 2 z + \sqrt{(x - 4) \frac{1}{2}} - 2 = 3 \cdot 3 \frac{1}{3 \cdot 2} + 3 x^{2} + 2 x - 5 y - 2 z

$- 5 y - 2 z + \sqrt{(x - 4) \frac{1}{2}} - 2 = 3 \cdot 3 \frac{1}{3 \cdot 2} + 3 x^{2} + 2 x - 5 y - 2 z$

Step 1.3.2.3

Cancel the common factor.

$- 5 y - 2 z + \sqrt{(x - 4) \frac{1}{2}} - 2 = 3 \cdot 3 \frac{1}{3 \cdot 2} + 3 x^{2} + 2 x - 5 y - 2 z$

Step 1.3.2.4

Rewrite the expression.

$- 5 y - 2 z + \sqrt{(x - 4) \frac{1}{2}} - 2 = 3 (\frac{1}{2}) + 3 x^{2} + 2 x - 5 y - 2 z$

Step 1.3.3

Combine

$3$ and

$\frac{1}{2}$ .

$- 5 y - 2 z + \sqrt{(x - 4) \frac{1}{2}} - 2 = \frac{3}{2} + 3 x^{2} + 2 x - 5 y - 2 z$

Step 2

Use

$\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite

$\sqrt{(x - 4) (\frac{1}{2})}$ as

${((x - 4) (\frac{1}{2}))}^{\frac{1}{2}}$ .

$- 5 y - 2 z + {((x - 4) (\frac{1}{2}))}^{\frac{1}{2}} - 2 = \frac{3}{2} + 3 x^{2} + 2 x - 5 y - 2 z$

Step 3

Since

$x$ is on the right side of the equation, switch the sides so it is on the left side of the equation.

$\frac{3}{2} + 3 x^{2} + 2 x - 5 y - 2 z = - 5 y - 2 z + {((x - 4) (\frac{1}{2}))}^{\frac{1}{2}} - 2$
