Solve this following

If $\overrightarrow{\mathrm{u}}, \overrightarrow{\mathrm{v}}, \overrightarrow{\mathrm{w}}$ are non-coplanar vectors and $\mathrm{p}, \mathrm{q}$ are real numbers, then the equality

$[3 \overrightarrow{\mathrm{u}} \mathrm{p} \overrightarrow{\mathrm{v}} \mathrm{p} \overrightarrow{\mathrm{w}}]-[\mathrm{p} \overrightarrow{\mathrm{v}} \overrightarrow{\mathrm{w}} \mathrm{q} \overrightarrow{\mathrm{u}}]-[2 \overrightarrow{\mathrm{w}} \mathrm{q} \overrightarrow{\mathrm{v}} \mathrm{qu}]=0$ holds for :-
