Step 2.4.4.1

Factor $2$ out of $2$ .

$v \frac{2 (87 + 52 \sqrt{2})}{2 (1)}$

Step 2.4.4.2

Cancel the common factor.

$v \frac{2 (87 + 52 \sqrt{2})}{2 \cdot 1}$

Step 2.4.4.3

Rewrite the expression.

$v \frac{87 + 52 \sqrt{2}}{1}$

Step 2.4.4.4

$v (87 + 52 \sqrt{2})$

Step 2.5

Apply the distributive property.

$v \cdot 87 + v (52 \sqrt{2})$

Step 2.6

Move $87$ to the left of $v$ .

$87 \cdot v + v (52 \sqrt{2})$

Step 3

Move $52$ to the left of $v$ .

$87 v + 52 v \sqrt{2}$
