Practice problem
Find the inverse of matrix A:
A=[−234−6]A = \begin{bmatrix} -2 & 3 \\ 4 & -6 \end{bmatrix}A=[−243−6]
A−1=[6−3−42]A^{-1} = \begin{bmatrix} 6 & -3 \\ -4 & 2 \end{bmatrix}A−1=[6−4−32]
A−1=[−326−4]A^{-1} = \begin{bmatrix} -3& 2 \\ 6 & -4 \end{bmatrix}A−1=[−362−4]
A−1=[2−3−46]A^{-1} = \begin{bmatrix} 2 & -3 \\ -4 & 6 \end{bmatrix}A−1=[2−4−36]
No Inverse
Type a concept, like “slope” or “photosynthesis”.
