Practice problem
If you add row 1 to row 2, then add row 2 to row 3, what is the resulting matrix?
A=[2302−2−3]A = \begin{bmatrix} 2 & 3 \\ 0 & 2 \\ -2 & -3 \end{bmatrix}A=20−232−3
A=[020000]A = \begin{bmatrix} 0 & 2 \\ 0 & 0 \\ 0 & 0 \end{bmatrix}A=000200
A=[230200]A = \begin{bmatrix} 2 & 3 \\ 0 & 2 \\ 0 & 0 \end{bmatrix}A=200320
A=[02−2−30−2]A = \begin{bmatrix} 0 & 2 \\ -2 & -3 \\ 0 & -2 \end{bmatrix}A=0−202−3−2
Type a concept, like “slope” or “photosynthesis”.
