Square root of a 2 by 2 matrix If "B" is zero but "A" and "D" are not both zero, one can use This formula will provide two solutions if "A" = "D" or "A" = 0 or "D" = 0, and four otherwise. A similar formula can be used when "C" is zero but "A" and "D" are not both zero. Square root of a 2 by 2 matrix A square root of a 2×2 matrix "M" is another 2 by 2 matrix "R" such that "M" = "R", where "R" stands for the matrix product of "R" with itself. In general there can be no, two,
