Step 1.1.1.2.1

Factor $2$ out of $2$ .

$v - \frac{2 (5 \sqrt{1})}{2 (1)} + 21 = 0$

Step 1.1.1.2.2

Cancel the common factor.

$v - \frac{2 (5 \sqrt{1})}{2 \cdot 1} + 21 = 0$

Step 1.1.1.2.3

Rewrite the expression.

$v - \frac{5 \sqrt{1}}{1} + 21 = 0$

Step 1.1.1.2.4

Divide $5 \sqrt{1}$ by $1$ .

$v - (5 \sqrt{1}) + 21 = 0$

$v - (5 \sqrt{1}) + 21 = 0$

$v - (5 \sqrt{1}) + 21 = 0$

Step 1.1.2

Any root of $1$ is $1$ .

$v - (5 \cdot 1) + 21 = 0$

Step 1.1.3

Multiply $- (5 \cdot 1)$ .

Step 1.1.3.1

Multiply $5$ by $1$ .

$v - 1 \cdot 5 + 21 = 0$

Step 1.1.3.2

Multiply $- 1$ by $5$ .

$v - 5 + 21 = 0$

$v - 5 + 21 = 0$

$v - 5 + 21 = 0$

Step 1.2

Add $- 5$ and $21$ .

$v + 16 = 0$

$v + 16 = 0$

Step 2

Subtract $16$ from both sides of the equation.

$v = - 16$
