Answer:
p² - p - 8 = prime trinomial
Step-by-step explanation:
p² - p - 8
You need to first find all the factors of -8 because that's the coefficient for the first and third term (1 * -8)
Factors:
Out of all these factors, you must find the two that add to -1 (the coefficient of the middle term).
In this example, none of these factors add to -1 so this expression is a prime trinomial.
