Initial Comment:
does anybody why all those "9999999" appear ?

(%i14) s^4+3.3*s^3+25.94*s^2+85.1*s;
(%o14) s^4+3.3*s^3+25.94*s^2+85.09999999999999*s

change the 8 to 5 or lower and it will disappear.

best regards

Message:
This is because 85.1 cannot be represented exactly in (IEEE) floating point
format.

If you want exact numbers use 851/10.

This is not a problem with maxima.  Marking as pending/invalid.
