Step 1.1

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

$p (2) = 4 \cdot 4 - 2 \cdot 2 - 13$

Step 1.2

Multiply $4$ by $4$ .

$p (2) = 16 - 2 \cdot 2 - 13$

Step 1.3

Multiply $- 2$ by $2$ .

$p (2) = 16 - 4 - 13$

Step 1.4

Subtract $4$ from $16$ .

$p (2) = 12 - 13$

Step 1.5

Subtract $13$ from $12$ .

$p (2) = - 1$

$p (2) = - 1$

Step 2

Divide each term in $p (2) = - 1$ by $2$ and simplify.

Step 2.2.1.1

Cancel the common factor.

$\frac{p \cdot 2}{2} = \frac{- 1}{2}$

Step 2.2.1.2

Divide $p$ by $1$ .

$p = \frac{- 1}{2}$

$p = \frac{- 1}{2}$

$p = \frac{- 1}{2}$

Step 2.3

Simplify the right side.

Step 2.3.1

Move the negative in front of the fraction.

$p = - \frac{1}{2}$

$p = - \frac{1}{2}$

$p = - \frac{1}{2}$

Step 3

The result can be shown in multiple forms.

Exact Form:

$p = - \frac{1}{2}$

Decimal Form:

$p = - 0.5$
