What exactly is gens here? I thought it was supposed to be a list that
contains all the symbols in the polynomials, but then I eventually run
into this error
/tmp/mattpap-sympy-polys-cd30a32/sympy/polys/polytools.py in
_init_poly_from_list(list_rep, *gens, **args)
286
287 if len(gens) != 1:
--> 288 raise PolynomialError("can't create a multivariate
polynomial from a list")
Thanks,
