Rearranging the skein relation, we see that:

Failed to parse (unknown function "\doublepoint"): {\displaystyle J(\doublepoint)=x(...)}

Analogously,

Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle J(\doublepoint ... \doublepoint)=x^{n+1}(...)}

for n+1 double points. In particular, the coefficient of $x^{n}$, $J_{n}$, will be zero when evaluated on a knot with $k+1$ crossings.
