Step 1.1.1

Factor $16$ out of $96$ .

$\sqrt{5} (2 \sqrt{6 x} - \sqrt{16 (6) x})$

Step 1.1.2

Rewrite $16$ as $4^{2}$ .

$\sqrt{5} (2 \sqrt{6 x} - \sqrt{4^{2} \cdot 6 x})$

Step 1.1.3

Rewrite $4$ as $2^{2}$ .

$\sqrt{5} (2 \sqrt{6 x} - \sqrt{{(2^{2})}^{2} \cdot 6 x})$

Step 1.1.4

Add parentheses.

$\sqrt{5} (2 \sqrt{6 x} - \sqrt{{(2^{2})}^{2} \cdot (6 x)})$

Step 1.2

Pull terms out from under the radical.

$\sqrt{5} (2 \sqrt{6 x} - (2^{2} \sqrt{6 x}))$

Step 1.3

Raise $2$ to the power of $2$ .

$\sqrt{5} (2 \sqrt{6 x} - (4 \sqrt{6 x}))$

Step 1.4

Multiply $4$ by $- 1$ .

$\sqrt{5} (2 \sqrt{6 x} - 4 \sqrt{6 x})$

Step 2

Subtract $4 \sqrt{6 x}$ from $2 \sqrt{6 x}$ .

$\sqrt{5} (- 2 \sqrt{6 x})$

Step 3
