Pre-Algebra Examples

$P (x) = {(- 3)}^{3} - 4 {(- 3)}^{2} - 7$

Step 1

Raise $- 3$ to the power of $3$ .

$P (x) = - 27 - 4 {(- 3)}^{2} - 7$

Step 2

Raise $- 3$ to the power of $2$ .

$P (x) = - 27 - 4 \cdot 9 - 7$

Step 3

Multiply $- 4$ by $9$ .

$P (x) = - 27 - 36 - 7$

Step 4

Subtract $36$ from $- 27$ .

$P (x) = - 63 - 7$

Step 5

Subtract $7$ from $- 63$ .

$P (x) = - 70$
