A) Find an equation in the form ax^2+bx+c=0 that can be used to determine the first year in which the population of US prisons was approximately 1216 people.
P(x) = 2x^2+18x+332

Solve:
2x^2+18x+332-1216 = 0
2x^2 + 18x - 884 = 0

---------------------
B)Now factor the equation to solve it and specify the first year in which the population was approximately 1216 thousand people.
x^2 + 9x - 442 = 0
(x-17)(x+26) = 0
---
Positive solution:
x = 17 years
