WebFinal answer. Diagonalize the following matrix. The real eigenvalues are given to the right of the matrix. ⎣⎡ 1 −1 1 2 4 −2 −4 −4 6 ⎦⎤;λ = 2,7 Select the correct choice below and, if … WebMay 31, 2024 · So, all you have to do is to diagonalize the matrix. B = [ 3 4 0 4 3 0 0 0 5]. Its characteristic polynomial is − x 3 + 11 x 2 − 23 x − 35 and, from the third column of B, you know that 5 is a root of this polynomial. Dividing the characteristic polynomial by x − 5, what you get is − x 2 + 6 x + 7, whose roots are − 1 and 7. WebWith the following method you can diagonalize a matrix of any dimension: 2×2, 3×3, 4×4, etc. The steps to diagonalize a matrix are: Find the eigenvalues of the matrix.
