Which polynomial is factored completely?

a) g^5 - g

b) 4g^3 + 18g^2 + 20g

c) 24g^2 - 6g^4

d) 2g^2 + 5g + 4

D) 2g² + 5g + 4 is the polynomial that is factored completely.

This is because the terms in the polynomial do not have any common factors.

a) g⁵ - g can be factored into g (g⁴ - 1)

b) 4g³ + 18g² + 20g can be factored into 2g (2g² + 9g + 10)

c) 24g² - 6g⁴ cab be factored into 6g² (4-g²)
