Hi, > Hello all. I've a problem, I'm trying to reorder a polynomial, which is obtained by substitution from this: > > Poly = Subscript[\[Alpha], 5] \! > \*SubsuperscriptBox[\(x\), \(1\), \(3\)] + Subscript[\[Alpha], 6] \! > \*SubsuperscriptBox[\(x\), \(2\), \(3\)] + Subscript[\[Alpha], 7] \! > \*SubsuperscriptBox[\(f\), \(1\), \(3\)] + Subscript[\[Alpha], 8] \! > \*SubsuperscriptBox[\(f\), \(2\), \(3\)] + Subscript[\[Alpha], 9] \! > \*SubsuperscriptBox[\(x\), \(1\), \(2\)] Subscript[x, 2] + Unfortunatly your example can't easily be copied to mathematica. You should convert any cell to InputForm before posting it here... >From the description of your problem I think the function Collect would do what you want... hth, albert
