Question: How do I extract the corresponding variables given the list of coefficients ?

November 04 2012 satya123999 20

I have a multivariate polynomial equation, in that somehow I know the coeffcients, using this information, I want to extract the variables. This will be the opposite of coeffs function.

for e.g. I have 3*x3 + 5*x4

Given 3 and 5, I want to extract x3 and x4.


Thanks in advance.
