If n2+2023n+2024n2+2023n+2024 is not a prime then n can be:

To determine the values of \( n \) for which the expression \( n^2 + 2023n + 2024 \) is not a prime number, we need to find values of \( n \) that make the expression composite (i.e., not prime).

The expression given is:
\[ P(n) = n^2 + 2023n + 2024 \]

We will start by checking if this polynomial can be factored for some values of \( n \).

1. **Factoring the Quadratic Expression:**
   \[
   P(n) = n^2 + 2023n + 2024
   \]
   To factor this, we look for two numbers that multiply to \( 2024 \) (the constant term) and add up to \( 2023 \) (the coefficient of \( n \)).

2. **Finding Factors:**
   We observe that:
   \[
   2023 = 2024 - 1
   \]
   Hence, we can rewrite the expression as:
   \[
   P(n) = n^2 + 2023n + 2024 = (n + 1)(n + 2024)
   \]

3. **Analyzing the Factors:**
   The expression \( (n + 1)(n + 2024) \) is a product of two integers. For \( P(n) \) to be not prime, both factors must be greater than 1 or one of them should be 1 or both negative.
   
   - If \( n + 1 = 1 \), then \( n = 0 \).
   - If \( n + 2024 = 1 \), then \( n = -2023 \).

Thus, we found that:
- When \( n = 0 \), \( P(n) = 2024 \), which is not a prime.
- When \( n = -2023 \), \( P(n) = 1 \), which is not a prime.

Since \( n \) can take any integer value and the factors \( (n + 1) \) and \( (n + 2024) \) must ensure the product is not prime, any value of \( n \) that makes \( n + 1 \) or \( n + 2024 \) a non-prime value will make \( P(n) \) non-prime.

Therefore, \( n \) can be \( 0 \) or \( -2023 \).
