Is 12n2+12n+1 prime over the set of polynomials with rational coefficients? Need help ASAP

No, the given polynomial is not prime.

Step-by-step explanation:

Given: a polynomial

To check: whether the given polynomial is prime or not.

Solution:

A prime polynomial is a polynomial that cannot be factored into polynomials of lower degree and has integers as coefficients.

In the given polynomial, coefficients are integers.

Also, the polynomial cannot be factored further into polynomials of lower degree.

So, the given polynomial is not prime.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
