@hazel the whole explanation at the bottom is basically just the definition of eigenvalues. The "A is acting on a real vector space R^2" part is just how the matrix A is defined, which should be part of the problem statement. The formula at the top is the formula for finding eigenvalues, which follows directly from the definition of eigenvalues. It's really not as bad as it looks, linear algebra's much easier than calculus imo
