$\"\"$

The polynomial is $\"\"$ .

In this trinomial, $\"\"$ . You need to find two numbers with a sum of $\"\"$ and a product of $\"\"$ . Make a list of the factors of 120 and look for the of factors with the sum of $\"\"$ .

$\"\"$

There are no factors with a sum of 5. So the quadratic expression cannot be factored using integers. Therefore, $\"\"$ is prime. $\"\"$
