: : x = (8 +- sqrt(928 - 18k)) / 18
: perhaps it is because some of us want to know all four solutions; real, complex, rational, integer, et.al.
...it does tell you stuff like: k must be < 52 (18*52=936) in order for
solution to be real...
would be useful as an analysis tool if this equation had to be programmed
in a real number "looper": if x^4 - x^3 > 51 then get d'hell outta here...
right, Joel :)
(for me anyway: I still use an old 486)
