Answer

$\left[\begin{matrix} -4& 2 &-5\\ 3& -1 &8 \end{matrix}\right]$

Work Step by Step

The given matrices are $A=\left[\begin{matrix} 0& 3 &-5\\ 1& 2 &6 \end{matrix}\right]$ $B=\left[\begin{matrix} 4& 1 &0\\ -2& 3 &-2 \end{matrix}\right]$ Subtract corresponding entries/elements. $\Rightarrow A-B=\left[\begin{matrix} 0-4& 3-1 &-5-0\\ 1-(-2)& 2-3 &6-(-2) \end{matrix}\right]$ Simplify. $\Rightarrow A-B=\left[\begin{matrix} -4& 2 &-5\\ 1+2& -1 &6+2 \end{matrix}\right]$ $\Rightarrow A-B=\left[\begin{matrix} -4& 2 &-5\\ 3& -1 &8 \end{matrix}\right]$.
