Question

Which polynomial is prime?

x2 + 9
x2 – 25
3x2 – 27
2x2 – 8

Answer 1

x^2+9 is the correct answer.i just took the test on edge

Explanation:

Answer 2

A prime polynomial is one that cannot be reduced.
x² - 25 reduced to (x + 5)(x - 5)
3x² - 27 reduces to 3(x + 3)(x - 3)
2x² - 8 reduces to 2(x + 2)(x - 2)

Therefore,
x² + 9 is prime.
