 Manipulate the real variables and look for solutions of the form [α 1 …    space of its associated eigenvectors (i.e., its eigenspace). We next need to determine the eigenvalues and eigenvectors for \(A\) and because \(A\) is a \(3 \times 3\) matrix we know that there will be 3 eigenvalues (including repeated eigenvalues if there are any).    
 See the graphs below for examples of graphs of polynomial functions with multiplicity 1, 2, and 3.    there are no repeated eigenvalues and, as a consequence, no defective
