Given a square matrix A: A= 2 (1.2) We perform the operation 3 -1 1-3 ki (1.1) We perform the operation R-R-2R Find the matrices E, and B such that EA= B (Hint: Find E, then perform E, A to obtain the matrix B). Find value(s) for k [-1,0] (whenever possible) such that 233= where [a] 13 are the entries of the matrix A given above. R R Find the matrices E and C such that A = EC (Hint: Find E then perform EA from which you should be able to obtain the matrices E and C). (3) (3)
