What is the depressed polynomial for f(x) with an obvious root?

[lucifer_x]

how would i write the depressed polynomial for the obvious root of

f(x) = x⁵ - .5x⁴ - 5.5x³ - 3.5x² - 6.5x - 3

I am afraid you are going to have to define the term "depressed polynomial". I confess I don't recognize it. (Which makes me depressed!). I will also confess that I don't, offhand, see an "obvious" root to that polynomial!

Use rational roots theorem, you only have 4 roots to try.
