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:

  • 1, -8
  • -1, 8
  • 2, -4
  • -2, 4

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.
