1. **State the problem:**
We need to verify and understand the equation $$n^3 + 2 = n(n + 1)(n - 1) + 2$$ where $n \in \mathbb{N}$.
2. **Recall the formula:**
The expression $n(n+1)(n-1)$ represents the product of three consecutive integers centered at $n$. This can be simplified using algebraic identities.
3. **Simplify the right-hand side:**
$$n(n+1)(n-1) = n \times (n^2 - 1) = n^3 - n$$
4. **Rewrite the original equation using this simplification:**
$$n^3 + 2 = (n^3 - n) + 2$$
5. **Subtract $n^3 + 2$ from both sides to check equality:**
$$n^3 + 2 - (n^3 - n + 2) = 0$$
$$n^3 + 2 - n^3 + n - 2 = 0$$
$$n = 0$$
6. **Interpretation:**
The equation holds true if and only if $n = 0$. However, since $n \in \mathbb{N}$ (natural numbers), and typically $\mathbb{N} = \{1, 2, 3, ...\}$, the equation is not true for any natural number.
**Final answer:** The equation $$n^3 + 2 = n(n + 1)(n - 1) + 2$$ is false for all natural numbers $n$ except possibly $n=0$ which is not in $\mathbb{N}$ under the usual definition.
