Show that the following superposition state in the |l,m1;ms> basis:-(2/3)^1/2|1,-1;1/2> + (1/3)^1/2|1,0;-1/2> is an eigenstate of J^2 and L * S and determine the corresponding eigenvalues.(adsbygoogle = window.adsbygoogle || []).push({});

I have no clue how to start this. Any help would be appreciated.
