Q1.
(a) Let V be a vector space over the field mathbb{R} and let T: V o V be a linear transformation. If T is such that T2 - 3T + 2I = 0, where I is the identity transformation, show that T is diagonalizable.
(b) Let A = \beginpmatrix 1 & 2 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \endpmatrix. Find the Jordan canonical form of A.
(c) Let f(x) = x3 - 6x2 + 11x - 6. Find the eigenvalues and eigenvectors of the matrix A = \beginpmatrix 1 & 2 & 0 \\ 2 & 1 & 0 \\ 0 & 0 & 3 \endpmatrix.
(d) Let V be the vector space of all polynomials of degree at most 2. Define a linear transformation T: V o V by T(p(x)) = p'(x) + p(x). Find the matrix representation of T with respect to the basis {1, x, x2}.
(e) Let A be an n imes n matrix such that A2 = A. Show that A is diagonalizable.
