Question
For the subspace below, (a) find a basis, and (b) state the dimension.

\[
\left\{
\begin{bmatrix}
6a + 12b - 2c \\
12a - 4b - 4c \\
-3a + 5b + c \\
-3a + b + c
\end{bmatrix}
: a, b, c \in \mathbb{R}
\right\}
\]

a. Find a basis for the subspace.

A basis for the subspace is □.  
(Use a comma to separate vectors as needed.)

b. State the dimension.

The dimension is □.
