Answer 2

To evaluate the expression 2p^3 - (p - 4 + 2p^3) when p = 3, we substitute the value of p into the expression and perform the necessary calculations.

Let's start by substituting p = 3:

2(3)^3 - (3 - 4 + 2(3)^3)

Simplifying the exponents:

2(27) - (3 - 4 + 2(27))

Performing the multiplications:

54 - (3 - 4 + 54)

Simplifying the addition and subtraction within the parentheses:

54 - (3 - 4 + 54) = 54 - (3 - 4 + 54) = 54 - (57)

Now, applying the subtraction:

54 - 57 = -3

Therefore, when p = 3, the value of the expression 2p^3 - (p - 4 + 2p^3) is -3.
