WebTake the zero matrix for B. Or, construct a matrix B such that the equation Bx = 0 has nontrivial solutions, and construct C and D so that C ≠ D and the columns of C - D satisfy the equation Bx = 0. Then B (C - D) = 0 and BC = BD. If AC=0, then either A=0 or C=0. False. If A and B are n x n, then (A+B) (A-B) + A^2 - B^2. False.
