1. The problem statement, all variables and given/known data Let T: M22 - M22 be defined by T(a b = 2c a + c c d) b-2c d (a) Find the eigenvalues T. (b) Find bases for the eigenspaces of T. 2. Relevant equations det(lambdaI - A) = 0 3. The attempt at a solution I just wanted to know how to start here. I am used to using vector transformations... Would I use identity matrices 1 0 0 1 0 0 0 0 0 0 0 0 1 0 0 1 And then form a matrix somehow? I just don't know how big or how this matrix would be formed...?
