Problem 1. (1) Orthogonally diagonalize the matrix A= (? 2 1 1 1 2 1 1 1 2 (2) Write down an expression for the quadratic form q(X1, X2, x3) = xAx as a function of X1, X2, X3 E R. (3) Determine the type of the quadratic form q. Justify your arguments. (4) Find an orthogonal matrix Q such that the coordinates change y = Qx transforms the quadratic form q into a sum of squares ay,2 + by22 +cy,
