2001 is the year Half Life came out for PlayStation.
495 leap years since year 0 (not including 0) (2001/4 = 500 R1 (drop R); 2000/400 = 5, 500 -5 = 495) (every four hundred years a leap year is not counted)
4 + 9 + 5 = 18
Make it a complex trinomial (3 terms; see where I’m going with this?), drop 18 for now so the discriminant formula can be used easily
4x^2 + 9x +5 = 0
Using the discriminant formula : b^2 – 4ac
9^2 – 4(4)(5)
81 – 80 = 1
D > 0 Therefore there are two real roots
Using the quadratic formula:
X = -1.25, x = -1
SUM OF ROOTS: -2.25
-2.25 x -1 (root) = 2.25
Bring back 18 from 4 + 9 + 5
18 / 2.25 = 8
5 leap years knocked off (400, 800, 1200, 1600, 2000; remember 0 is not counted)
8 – 5 is 3.
HALF LIFE 3 CONFIRMED.
