Question

$$P-2=3(-2)^{3}-5(-2)^{2}+7(-2)-10$$

Solve for P

$P=-66$

Steps for Solving Linear Equation

Calculate $-2$ to the power of $3$ and get $-8$.

$$P-2=3\left(-8\right)-5\left(-2\right)^{2}+7\left(-2\right)-10$$

Multiply $3$ and $-8$ to get $-24$.

$$P-2=-24-5\left(-2\right)^{2}+7\left(-2\right)-10$$

Calculate $-2$ to the power of $2$ and get $4$.

$$P-2=-24-5\times 4+7\left(-2\right)-10$$

Multiply $5$ and $4$ to get $20$.

$$P-2=-24-20+7\left(-2\right)-10$$

Subtract $20$ from $-24$ to get $-44$.

$$P-2=-44+7\left(-2\right)-10$$

Multiply $7$ and $-2$ to get $-14$.

$$P-2=-44-14-10$$

Subtract $14$ from $-44$ to get $-58$.

$$P-2=-58-10$$

Subtract $10$ from $-58$ to get $-68$.

$$P-2=-68$$

Add $2$ to both sides.

$$P=-68+2$$

Add $-68$ and $2$ to get $-66$.

$$P=-66$$
