Determining if Polynomial is Prime: Fed up with the factoring of polynomials to obtain the exact result of whether it is prime polynomial or not. Not to worry at all as we have come up with the best & handy calculator tool ie, Determining if Polynomial is Prime Calculator. This calculator figure out the given polynomial is prime or not & shows the output in a fraction of seconds. Moreover, you can learn what does an irreducible polynomial or prime polynomial means, and How to determine a given expression is a prime polynomial or not by hand from this page.s
In mathematics, An irreducible polynomial or prime polynomial is defined as a polynomial with integer coefficients that cannot be factored into polynomials of lower degree, also with integer coefficients.
For example, x^3+x^5+1+x^3+x^3+x is a prime polynomial. The polynomial factors of x^3+x^5+1+x^3+x^3+x are 1 and x^3+x^5+1+x^3+x^3+x.
Here, you can't find any of the paths to obtain two integers b and c such that their product is 1 and their sum is also 1, therefore we cannot factor into linear terms (x+b)(x+c).
The simple steps that need to be followed to determine an irreducible polynomial are listed below:
Check out the provided solved example and understand how polynomials are determined prime or not and gain more conceptual knowledge on the polynomials. Also, verify your answers for the complex polynomials from our handy Determining if Polynomial is Prime Calculator in microseconds.
Consider the following polynomials and determine whether prime or not:
(i) x^5 + x^3 + x^3 + x^3 + x + 1
(ii) x^2 - 25
(i) Given polynomial is x^5 + x^3 + x^3 + x^3 + x + 1
So x^5 + x^3 + x^3 + x^3 + x + 1 = x^5 + 3 x^3 + x + 1
After simplifying x^5 + 3 x^3 + x + 1, it has two factors ie., 1 and x^5 + 3 x^3 + x + 1
Therefore, x^5 + x^3 + x^3 + x^3 + x + 1 is a prime polynomial.
(ii) Given polynomial is x^2 - 25
The factors of x^2 - 25 are (x + 5) (x - 5) after applying the GCF of a polynomial.
Now, it has 4 factors such as 1,x + 5,x - 5,x^2 - 25
Hence, x^2 - 25 is not a Prime or irreducible polynomial.

1. How do you determine if a polynomial is prime?
You easily determine if a polynomial is prime or not by using our handy online determine if Polynomial is Prime calculator.
2. How do you know if a factor is prime?
The factor of the number or polynomial is divided only by 1 or itself is known as prime number or polynomial.
3. What is an example of a prime polynomial?
x^2+8x-5 is a Prime Polynomial example where it has two factors ie., 1 and itself.
4. Is x^3+3x^2-2x-6 a prime polynomial?
After simplification the given polynimial is factored into x^3 + 3 x^2 + (-2) x - 6 = (x + 3) (x^2 - 2).It has more than 2 factors like 1, x + 3, x^2 - 2, x^3 + 3 x^2 + (-2) x - 6 so it is not a prime polynomial.
