This is a characteristic equation in which I am trying to locate roots for E of the following polynomial:

2*b^3-3*b^2*a+3*b^2*E-3*a^2*E+3*a*E^2-E^3+a^3

Any help would be greatly appreciated!

I have just upgraded from Maple 12 to Maple 14.  I opened an old file (Maple 12 format) and when I tried to use display to replot the data - there were capital letters where the fit line should be and the axes were also strange.  Is anyone else having this problem and what should I do about it.  Below is a copy of my info:

  complexplot, complexplot3d, conformal, conformal3d,
