You could think of this as factoring the difference of two squares (if you consider 75 as a "square"
the square root of 75 = 5 * sqrt(3)

We factor it as
(x + 5 * sqrt(3)) * (x -5 * sqrt(3)
and the roots are
- 5 * sqrt(3) and + 5 * sqrt(3)
so you have your function befor 2_75 but 75 years befor 2 years it would be =75 because of the timeline in order you use in a grafgh of 75_2=73 so 73 years befor 2007 was 75+75= 150 1998 is the awnser
