Step 1.1.1

Factor $16$ out of $112$ .

$6 x \sqrt{16 (7)} - 6 \sqrt{7 x^{2}}$

Step 1.1.2

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

$6 x \sqrt{4^{2} \cdot 7} - 6 \sqrt{7 x^{2}}$

$6 x \sqrt{4^{2} \cdot 7} - 6 \sqrt{7 x^{2}}$

Step 1.2

Pull terms out from under the radical.

$6 x (4 \sqrt{7}) - 6 \sqrt{7 x^{2}}$

Step 1.3

Multiply $4$ by $6$ .

$24 x \sqrt{7} - 6 \sqrt{7 x^{2}}$

Step 1.4

Reorder $7$ and $x^{2}$ .

$24 x \sqrt{7} - 6 \sqrt{x^{2} \cdot 7}$

Step 1.5

Pull terms out from under the radical.

$24 x \sqrt{7} - 6 x \sqrt{7}$

$24 x \sqrt{7} - 6 x \sqrt{7}$

Step 2

Subtract $6 x \sqrt{7}$ from $24 x \sqrt{7}$ .

$18 x \sqrt{7}$
