If A = [[1, 2], [3, 4]] and B = [[2, 4], [6, 8]], then 2A − B is: A. [[0, 0], [0, 0]] B. [[1, 0], [0, 1]] C. [[-1, -2], [-3, -4]] D. [[3, 6], [9, 12]] Answer: A) [[0, 0], [0, 0]] Explanation: 2A = [[2, 4], [6, 8]]. Subtracting B gives 2A − B = [[2−2, 4−4], [6−6, 8−8]] = [[0, 0], [0, 0]], which is a zero matrix.

imo class 12 matrices
