1\\3\\2

\end{bmatrix}$ is in the span $B=\left\{\begin{bmatrix}

2\\1\\0

\end{bmatrix}

\cdot

\begin{bmatrix}

1\\1\\1

\end{bmatrix}\right\}$

ok I added A and B to this for the OP

but from examples it looks like this can be answered by scalors so if

$c_1\begin{bmatrix}

2\\1\\0

\end{bmatrix}

+

c_2\begin{bmatrix}

1\\1\\1

\end{bmatrix}=\begin{bmatrix}

1\\3\\2

\end{bmatrix}$
