Practice problem
What is [abcdef]−[axcyez]=\begin{bmatrix} a & b & c \\ d & e & f \end{bmatrix}- \begin{bmatrix} a & x & c \\ y & e & z \end{bmatrix}=[adbecf]−[ayxecz]=
[0b−x0d−y0f−z]\begin{bmatrix} 0 & b-x & 0 \\ d-y &0 &f-z \end{bmatrix}[0d−yb−x00f−z]
[0x−b0y−d0z−f]\begin{bmatrix} 0 & x-b & 0 \\ y-d &0 &z-f \end{bmatrix}[0y−dx−b00z−f]
[ab−xcd−yef−z]\begin{bmatrix} a & b-x & c \\ d-y &e &f-z \end{bmatrix}[ad−yb−xecf−z]
You can't solve this.
Type a concept, like “slope” or “photosynthesis”.
