Answer:
p^2 - 16p - 80
Vieta's formulas
because 4 * (-20) = -80 and 4 + (-20) = -16
p^2 - 16p - 80 = (p + 4)(p - 20)
Answer:
(p - 20)(p + 4).
Step-by-step explanation:
p^2 - 16p - 80
We need 2 numbers whose product is -80 and whose sum is -16. They are -20 and + 4.
So we have the result p^2 - 16p = 80 = (p - 20)(p + 4).
