$v = - 2 i - 2 j$ , $\frac{1}{2} v$

Step 1

Reorder $- 2 i$ and $- 2 j$ .

$v = - 2 j - 2 i$

Step 2

Replace the variable $v$ with $- 2 j - 2 i$ in the expression.

$\frac{1}{2} \cdot (- 2 j - 2 i)$

Step 3

Apply the distributive property.

$\frac{1}{2} (- 2 j) + \frac{1}{2} (- 2 i)$

Step 4

Cancel the common factor of $2$ .

Step 4.1

Factor $2$ out of $- 2 j$ .

$\frac{1}{2} (2 (- j)) + \frac{1}{2} (- 2 i)$

Step 4.2

Cancel the common factor.

$\frac{1}{2} (2 (- j)) + \frac{1}{2} (- 2 i)$

Step 4.3

Rewrite the expression.

$- j + \frac{1}{2} (- 2 i)$

Step 5

Step 5.1

Factor $2$ out of $- 2 i$ .

$- j + \frac{1}{2} (2 (- i))$

Step 5.2

Cancel the common factor.

$- j + \frac{1}{2} (2 (- i))$

Step 5.3

Rewrite the expression.

$- j - i$
