Vedclass · Answer

(A) To add or subtract matrices,they must have the same order. Matrix $A$ is of order $3 	imes 3$. Matrix $B$ is of order $3 	imes 2$. In the expression $A^2 + 2B - 2A$,we are attempting to add matrix $A^2$ (which is $3 	imes 3$) to matrix $2B$ (which is $3 	imes 2$). Since the orders of $A^2$ and $2B$ are different,the addition is not defined. Therefore,the expression $A^2 + 2B - 2A$ is not defined.

If $A = \begin{bmatrix} 4 & 6 & -1 \\ 3 & 0 & 2 \\ 1 & -2 & 5 \end{bmatrix}$,$B = \begin{bmatrix} 2 & 4 \\ 0 & 1 \\ -1 & 2 \end{bmatrix}$,and $C = \begin{bmatrix} 3 \\ 1 \\ 2 \end{bmatrix}$,then which of the following expressions is not defined?
