Given a cross product:

$\overrightarrow{u}\times \overrightarrow{v}=\u27e8-1,1,-3\u27e9$

I'm trying to find:

$(\overrightarrow{u}-3\overrightarrow{v})\times (\overrightarrow{u}+2\overrightarrow{v})$ as a vector.

$\overrightarrow{u}\times \overrightarrow{v}=\u27e8-1,1,-3\u27e9$

I'm trying to find:

$(\overrightarrow{u}-3\overrightarrow{v})\times (\overrightarrow{u}+2\overrightarrow{v})$ as a vector.
