Find a formula for the Jones polynomial of the disjoint union of two diagrams $K_1$ and $K_2$ Find a formula for the Jones polynomial of the disjoint union of two diagrams $K_1$ and $K_2$.


I am having a lot of trouble with this seemingly easy question. I understand that a Jones polynomial looks like this: 

$$V_K(t) = L_K(t^{-1/4}), \text{where}$$ 
$$L_K(A) = (-A^3)^{- \omega (K)} \cdot \langle K \rangle$$

But I don't understand how to apply this to two disjoint diagrams. Any help would be appreciated. 

Update: Online resources have been telling me to using the Skein relation, and so I feel as if the approach I'm taking is not good.
$V(Sn)(t) = (-t^{-1/2} - t^{1/2})^{n-1}$ where $Sn$ is a n component unlink. This result comes from An Introduction to Quantum and Vassiliev Knot Invariants by David M. Jackson Iain Moffatt, P30.
