Step 1.3.2.1

Factor $3$ out of $9$ .

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

Step 1.3.2.2

Factor $3$ out of $6$ .

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

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.

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