False. Change statement to "$x^{2}+x+20$" is a prime trinomial.

Work Step by Step

If the trinomial $ax^{2}+bx+c$ can be factored, it will be in the form $(x+n)(x+m)$, where the product of integers n and m is $c$ their sum is $b.$ Factors of 20, both positive 1 and 20 ... sum =21, 2 and 10 ... sum =12 4 and 5 ... sum =9. No pair has sum =1. No factorization exists. The trinomial is prime. False. Change statement to "$x^{2}+x+20$" is a prime trinomial.
