The trinomial expression is
.
The trinomial compare to general trinomial expression:
, So a = 1, b = 6, c =
9.
To find two numbers with a sum of 6 and a product of
.
This trinomial list of the factors of
9, and look for the pair of factors is a sum of 6.

There are no factors with a sum of 6.
\Therefore,
cannot be factored using integers.
Thus,
is a prime polynomial.
The trinomial is a prime.
