Simplify each term.

Tap for more steps...

Step 1.1

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

$f (- 2) = 3 \cdot 4 - 3 \cdot - 2$

Step 1.2

Multiply $3$ by $4$ .

$f (- 2) = 12 - 3 \cdot - 2$

Step 1.3

Multiply $- 3$ by $- 2$ .

$f (- 2) = 12 + 6$

$f (- 2) = 12 + 6$

Step 2

Add $12$ and $6$ .

$f (- 2) = 18$
