C. [tex]4x^3 + 2x^2 + 6x + 3[/tex]

D. [tex]4x^3 + 4x^2 - 3x - 3[/tex]



Answer :

To determine which polynomial is prime, let’s define what it means for a polynomial to be prime. A polynomial is considered prime if it cannot be factored into the product of two non-constant polynomials with coefficients in the same field (usually rational numbers for this context).

We will analyze each polynomial to see if it can be factored or not.

1. Polynomial: [tex]\( 3x^3 + 3x^2 - 2x - 2 \)[/tex]

- First, we look for any common factors among the coefficients, and in this case, there are none other than 1.
- Next, we try common factoring techniques such as grouping or synthetic division, but these attempts lead us to conclude that the polynomial does not factor nicely into two non-constant polynomials with rational coefficients.

2. Polynomial: [tex]\( 3x^3 - 2x^2 + 3x - 4 \)[/tex]

- We inspect the coefficients and follow similar factorization strategies.
- Attempts at grouping or special factoring techniques do not yield a factorable form.
- We conclude that the polynomial does not factor into two non-constant polynomials with rational coefficients.

3. Polynomial: [tex]\( 4x^3 + 2x^2 + 6x + 3 \)[/tex]

- We check if it has any common factors among the coefficients, and it doesn’t.
- Upon trying various techniques including polynomial identities, grouping, or synthetic division, no factorable form emerges.
- Thus, this polynomial appears to not be factorable into two non-constant polynomials with rational coefficients.

4. Polynomial: [tex]\( 4x^3 + 4x^2 - 3x - 3 \)[/tex]

- We analyze the coefficients for common factors and find none.
- Using techniques of factorization doesn't yield any simpler forms or non-constant polynomial products.
- Consequently, this polynomial is concluded to not be factorable into two non-constant polynomials with rational coefficients.

After analyzing all four polynomials for prime factorization, we find that none of the polynomials can be factored into the product of two non-constant polynomials with rational coefficients.

Therefore, none of the given polynomials are prime, and the prime indices list is empty.

The conclusion is that none of the given polynomials are prime.
