Finding eigenvalues and eigenvectors of a non-defective 3x3 matrix

[@TC_seven_]

The part we came here for is the part you decided to use a calculator instead of showing us how it's done 😢

Are you referring to the part where we put the matrix into reduced row echelon form? If so, feel free to reference this playlist on the subject of elementary row operations, row echelon form, and reduced row echelon form:

(3-♤)(♤+1)= -♤^2+4♤+3

So... not really sure what you are intending with this comment, but it is definitely inaccurate. Expanding the left side would give -♠^2+2♠+3 rather than what we see on the right side of your equation.
