I have no work, these questions I don't know how to do...
If 1999 is a root of
x^3 - 1999x^2+x-1999=0
then a root of
(x-1)^3-1999(x-1)^2 +(x-1)-1999=0
is a value of x so that
x-1 = 1999
In other words, x=2000
x^3 - 1999x^2+x-1999=0
then a root of
(x-1)^3-1999(x-1)^2 +(x-1)-1999=0
is a value of x so that
x-1 = 1999
In other words, x=2000
