Default Spans
Find all values a for which \begin{bmatrix}1 \\ 1 \\ 1\end{bmatrix} is in the span of v_1,v_2,v_3. Also find the values of a for which v_1,v_2,v_3 are linearly independent.

v_1=\begin{bmatrix}1 \\ a \\ a\end{bmatrix} v_2=\begin{bmatrix}a \\ 1 \\ a\end{bmatrix} v_3=\begin{bmatrix}a \\ a \\ 1\end{bmatrix}

When I try to do rref I get all zeros in the bottom...
