Evaluate Using the Given Value f(-5)=(-5)^2-2*-5-7

$f (- 5) = {(- 5)}^{2} - 2 \cdot - 5 - 7$

Step 1

Simplify each term.

Raise $- 5$ to the power of $2$ .

$f (- 5) = 25 - 2 \cdot - 5 - 7$

Multiply $- 2$ by $- 5$ .

$f (- 5) = 25 + 10 - 7$

Step 2

Simplify by adding and subtracting.

Add $25$ and $10$ .

$f (- 5) = 35 - 7$

Subtract $7$ from $35$ .

$f (- 5) = 28$
