Web10 years ago. To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment. WebSep 8, 2015 · Which by getting to the form: [ 9 − λ 8 8 9 − λ] v = 0. and using the determinant of the matrix = 0, to get a quadratic equation to solve, you get the eigenvalues 1 and 17. If you substitute 17 back into the equation you get: [ − 8 8 8 − 8] v = 0. and end up with the simultaneous equations. − 8 v 1 + 8 v 2 = 0 and 8 v 1 − 8 v 2 = 0. earn discord nitroWebBasic functionality #.
