Practice problem
Solve [xyz]∗[598−502]\begin{bmatrix}x&y&z\end{bmatrix}*\begin{bmatrix}5&9\\8&-5\\0&2\end{bmatrix}[xyz]∗5809−52
[5x+8y9x−5y+2z]\begin{bmatrix}5x+8y&9x-5y+2z\end{bmatrix}[5x+8y9x−5y+2z]
[9x−5y+2z5x+8y]\begin{bmatrix}9x-5y+2z&5x+8y\end{bmatrix}[9x−5y+2z5x+8y]
[5x−5y9x+8y+2z]\begin{bmatrix}5x-5y\\9x+8y+2z\end{bmatrix}[5x−5y9x+8y+2z]
These cannot be multiplied.
Type a concept, like “slope” or “photosynthesis”.
