How many eigenvalues does a 3x3 matrix have

WebSep 17, 2024 · Therefore, the eigenvalues are 3 + 2√2 and 3 − 2√2. To compute the eigenvectors, we solve the homogeneous system of equations (A − λI2)x = 0 for each eigenvalue λ. When λ = 3 + 2√2, we have A − (3 + √2)I2 = (2 − 2√2 2 2 − 2 − 2√2) R1 = R1 × ( 2 + 2√2) → (− 4 4 + 4√2 2 − 2 − 2√2) R2 = R2 + R1 / 2 → (− 4 4 + 4√2 0 0) R1 = R1 ÷ − 4 → (1 … WebWhich is: (2−λ) [ (4−λ) (3−λ) − 5×4 ] = 0. This ends up being a cubic equation, but just looking at it here we see one of the roots is 2 (because of 2−λ), and the part inside the square brackets is Quadratic, with roots of −1 and 8. So …
