If the system of linear equations, x+y+z=6; x+2 y+3 z=10; 3 x+2 y+λ z=μ has more than two solutions, then μ-λ^2 is equal to \ \ \ \.
If the system of linear equations,
$$\begin{gathered}
x+y+z=6 \\
x+2 y+3 z=10 \\
3 x+2 y+\lambda z=\mu
\end{gathered}
$$
has more than two solutions, then $\displaystyle \mu-\lambda^2$ is equal to \_\_\_\_.
