Dur, at where it is lowest

at x=- and x=4

the values of the function where it has a minimum are at x=-2 and x=4

the local min values are y=-3 and y=-5

Have you been taught synthetic division. I don't think there is an easier way to do this.

- 1 || 1 3 5 3

-1 -2 -3

==============

1 2 3 0

So the answer becomes

Length = x^2 + 2x +3 which isn't very nice to factor, but it is the length. Long division will give you exactly the same answer. And this cannot be reduced further and still give answers in the real realm of numbers.
