I'm having a hard time understanding how they're getting these vectors from the matrix. I follow up to plugging in the eigenvalues and solving the variables, then I get lost for like the first one beta = alpha = 0. When I solve and plug in beta = 2*alpha = 2 * (2*beta) -> beta = 4beta, so is it zero because thats the only number that makes this equality? So like it's not so much algebra after solving as looking at the equality and making sense of it?
