Which polynomial is prime?
a)x3 + 3x2 – 2x – 6
b)x3 – 2x2 + 3x – 6
c)4x4 + 4x3 –2x – 2
d)4x4 + 2x3 –2x + 4

is a prime polynomial.

Step-by-step explanation:

Given some polynomials we have to choose the polynomial which is prime.

A prime polynomial is a polynomial with integer coefficients that cannot be factored lower degree polynomials or simply we can say prime polynomial is a polynomial that can't be factored.

Option A:

∴ can be factored as

Option B:

∴ can be factored as

Option C:

∴ can be factored as

Option D:

The above polynomial can't be factored.

Hence,   is a prime polynomial.

Option D is correct.

4x and 6y

im not sure though

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
