Question textLet [math: A=[210−10−12−14]]A={\left[\begin{array}{ccc} 2 & 1 & 0 \\ -1 & 0 & -1 \\ 2 & -1 & 4 \end{array}\right]}. Find an eigenvector of [math: A] and its corresponding eigenvalue. Note: You don't have to find all eigenvalues and eigenvectors, just a single one will suffice. [table] | | | | | | [/table] Your last answer was interpreted as follows: [math: [1−10]] \left[\begin{array}{c} 1 \\ -1 \\ 0 \end{array}\right] is an eigenvector with eigenvalue [input] Your last answer was interpreted as follows: [math: 1] .多项填空题
