    To make sure the polynomial can be factored at all, I "cheated" and used this site:
http://firstyear.chem.usyd.edu.au/calculators/quartic.shtml
It cannot be factored into monomials with real rational constants.
The four roots of
6x^4-5t^3-200t-163000 = 0
are
13.10, -12.59
and
0.1577 +/- 12.83i
Approximate factors are:
6(x-13.10)(x+12.59)(x -0.1577 -12.83i)(x-0.1577 +12.83i)
