Is x^2+3 free of x^6? Ordinarily I would think that if E is free of v, then one could vary v in any way, and not affect the value of E. If one varies x^6, it is kind of difficult to keep x^2+3 constant.
I suppose you could specify a program to search in an expression to see if x^6 occurs as a distinct subcomponent, but it probably wouldn't be too useful. For example, does x^6 occur in x*(x^5+1)? I suggest you require that the value of v be a symbol.
