    this trinomial is prime, and cannot be factored.

    Step-by-step explanation:

    when expanding the equation, you multiply the last term by the first term's coefficient, and then find two factors that multiply to that product, and sum to the middle coefficient.

    1 * 19 = 19

    there are no factors that will multiply to 19 and sum to 11. thus, this polynomial is prime.
