$\"\"$

The trinomial is $\"\"$ .

The general form of quadratic expression is $\"\"$ .

In this trinomial $\"\"$ and $\"\"$ .

Find two numbers with a sum of $\"\"$ and a product of $\"\"$ .

Make a list of the factors of $\"\"$ and look for the of factors with the sum of $\"\"$ .

$\"\"$

There are no factors with a sum of $\"\"$ .

So, the quadratic expression can not be factored using integers.

Therefore, the polynomial expression $\"\"$ is prime.
