I have an equation :
Using coeffs(), i get their coefficients, flip them left to right and then use roots() function to get its zeroes.
But, when , coeffs() function gives coeffs of non-zero terms only,
that is, for fliplr(coeffs(fn)) = [a,c,e,g,i]
So, when I put this coeffs() solution in roots(), it considers it as fifth order polynomial.
How can I get around this problem?

Specify the 'All' option in your call to coeffs to return all the coefficients, even those that are 0.
