Answer:
2x³- 2px² + p + 2
First plug in x = -3
2(-3)³- 2p(-3)² + p + 2
According to PEMDAS, we should solve the exponents first.
(-3)³ = -27
(-3)² = 9
2(-27) - 2(9)p + p + 2
Now multiply.
-54 - 18p + p + 2
Now combine the variables and constants.
-17p - 52
This is the simplified expression.
If it is an equation, then it would equal 0.
-17p - 52 = 0
To solve for p, add 52 to both sides.
-17p = 52
Now isolate the p by dividing by -17.
p = -52/17 or -3.0589
