hendrisyafa $K-L= \left[\begin{array}{ccc}1&3\\2&1\\\end{array}\right] -\left[\begin{array}{ccc}2&1\\0&4\\\end{array}\right]= \left[\begin{array}{ccc}-1&2\\2&-3\\\end{array}\right]$

$(K-L)^{2}= \left[\begin{array}{ccc}-1&2\\2&-3\\\end{array}\right] ^2$

$(K-L)^{2}= \left[\begin{array}{ccc}-1&2\\2&-3\\\end{array}\right] . \left[\begin{array}{ccc}-1&2\\2&-3\\\end{array}\right]$

$(K-L)^{2}= \left[\begin{array}{ccc}5&-8\\-8&13\\\end{array}\right]$
