If x1 maximizes a quadratic form, subject to the constraint ||x1||=1, then - so does -x1 If A= A^T x != y, Ax = 3x, and Ay = -y, then - x^Ty = 0 S = {x exists in R^3 | x1 + x2 + x3 = 1}, then - is not a subspace of R^3 If U is an echelon form of matrix A, then - Col(U) != Col(A) Row operations on a nxn matrix do change - its eigenvalues. IF A exists in R^nxn and x and y are vectors in R^n, then Ax * Ay = - x^T(A^T)Ay If the eigenvalues of a 3x3 matrix A are 1,2,4 and A = PBP^-1 for 3x3 mat...
