Final answer:
The value of 2|6 + p| - 3p³ when p = -2 is calculated by substituting -2 into the expression, simplifying, and combining values to obtain a result of 32.
Step-by-step explanation:
To find the value of 2|6 + p| - 3p³ when p = -2, follow these steps:
- Substitute p with -2 into the expression: 2|6 + (-2)| - 3(-2)³.
- Calculate the absolute value |4|, which is 4.
- Multiply the absolute value by 2: 2 × 4 to get 8.
- Calculate the cube of -2: (-2)³, which is -8.
- Multiply this result by -3: -3 × -8 to get 24.
- Finally, add the two results together: 8 + 24 to get 32.
Therefore, when p = -2, the value is 32.
