Check Sort the polynomials according to whether they are prime or non-prime.
6x3 - 5x2 + 2x-14
124 - 18x2 + 8x2 - 12
6x2 + 9x + 10x + 15
1272 - 3x + 4x +7

first, second and fourth are primes, the third is not-prime.

Step-by-step explanation:

A prime polynomial can not be reduced.

Let's see the options:

A) 6x^3 - 5x^2 + 2^x-14

You can see that we have a coefficient equal to 5 and other equal to 2.

As both are prime numbers, we can not reduce this, so this is a prime polynomial.

B) 12x^4 - 18x^2 + 8x^2 - 12 = 12x^4 -10*x^2 + 124

Both coefficients are even, so we can reduce it to:

12x4 -10*x^2 + 124 = 2*(6x^4 -5*x^2 + 72)

So this is not prime.

C) 6x^3 + 9x^2 + 10x + 15

we have that:

6 = 3*2

9 = 3*3

10 = 2*5

15 = 3*5

a polinomial is only reducible if all the coefficients share at least one prime factor, here we can see that this is not the case, so this is a prime polinomial.

D) 12x^2 -3x + 4x + 7 = 12x^2 + x + 7

Again, here we have that one coefficient is 1, the only factor of 1 is itself, so we can not reduce this polinomial, this is prime.
