Which polynomials are prime? check all that apply.
15x2 + 10x – 9x + 7
20x2 – 12x + 30x – 18
6x3 + 14x2 – 12x – 28
8x3 + 20x2 + 3x + 12
11x4 + 4x2 – 6x2 – 16

The prime polynomials are 1, 4 and 5

Step-by-step explanation:

Given some polynomials we have to classify the polynomials prime or not.

Prime polynomials are the polynomial with integer coefficients that cannot be factored into lower degree polynomials.

⇒

can't be factored into lower degree polynomial ∴ prime polynomial.

⇒

⇒

hence, not a prime polynomial.

⇒

hence, not a prime polynomial.

⇒

can't be factored into lower degree polynomial ∴ prime polynomial.

⇒

can't be factored into lower degree polynomial ∴ prime polynomial.

The prime polynomials are 1, 4 and 5

after simplifying it i got: -36.25 as my answer. hope that !
