Answer:
A and B
Step-by-step explanation:
- A polynomial with integer coefficients that cannot be factored into polynomials of lower degree, also with integer coefficients, is called an irreducible or prime polynomial
As per above definition, A and B polynomials have coefficients 1 or 3, so are prime polynomials.
C and D polynomials have coefficient of 6 which can be further factored
A. x^4 + 3x^2 – x^2 – 3
B. x^4 – 3x^2 – x^2 + 3
C. 3x^2 + x – 6x – 2
D. 3x^2 + x – 6x + 3
