Finding basis for an eigenspace
1. The problem statement, all variables and given/known data
Find a basis and dimension for each eigenspace of the matrix: 4 2 3 3 2. Relevant equations 3. The attempt at a solution I found the eigenvalues lambda = 1, 6. When trying to find the eigenspace for lambda = 1, I try to solve for x and y here: |-3 -2| |x| = |0| |-3 -2| |y| = |0| I'm not sure how to do the matrix notation on here but I hope it is clear enough. Since I get the same equation twice in the system of equations, is this the right basis: span(-2/3, 1)? edit: can someone also see if I did the basis for the 2nd eigenvalue (lambda = 6) correctly? I get the basis to be span(1, 1). So each has dimension of 1 |

Um, yes. If I'm reading your notation correctly, you have the right eigenspace for both. Is this a question, or just a homework check?

It was originally going to be a question but I kind of figured it out as I was typing it :)
So I was just making sure. Thanks |
