Select the correct answer.
Which expression is a prime polynomial?

A. X^3 - 1
B.X^2 + 1
C.X^3 + 1
D.X^2 - 1

Answer 1

Answer: The correct answer is D, X^2 - 1.

A prime polynomial is a polynomial that has no real or complex roots (i.e., no solutions), except for 0. X^2 - 1 has two roots, -1 and 1, both of which are not 0. Hence, it is a prime polynomial.
