Answer:  C = \begin{bmatrix} -3 &4 &-1 \\ -3& 0 &-1 \end{bmatrix}

Hint: Zero matrix is \begin{bmatrix} 0 &0 \\ 0& 0 \end{bmatrix} 

Add A and B matrices. Then, find C.

Given: A =\begin{bmatrix} 1 &-3 &2 \\ 2 & 0 &2 \end{bmatrix} , B =\begin{bmatrix} 2 &-1 & -1\\ 1& 0 & -1 \end{bmatrix} , A + B + C = 0

Here, we have to compute C.

Solution:

A + B + C =\begin{bmatrix} 0 &0 &0 \\ 0& 0 & 0 \end{bmatrix}

\begin{bmatrix} 1 & -3 &2 \\ 2 &0 &2 \end{bmatrix} +\begin{bmatrix} 2 & -1&-1 \\ 1& 0 & -1 \end{bmatrix} + C = \begin{bmatrix} 0 &0 &0 \\ 0& 0& 0 \end{bmatrix}

\begin{bmatrix} 3 & -4 &1\\ 3 &0 &1 \end{bmatrix} + C = \begin{bmatrix} 0 &0 &0 \\ 0& 0& 0 \end{bmatrix}

C = \begin{bmatrix} 0 &0 &0 \\ 0& 0& 0 \end{bmatrix}-\begin{bmatrix} 3 & -4 &1\\ 3 &0 &1 \end{bmatrix}

C = \begin{bmatrix} -3 &4 &-1 \\ -3& 0 &-1 \end{bmatrix}
