Suppose we have matrices:<br/>A = \(\left(\begin{vmatrix}1&amp;-1\\2&amp;3\end{vmatrix}\right)\) and B = \(\left(\begin{vmatrix}0&amp;2\\4&amp;3\end{vmatrix}\right)\)<br/>Find \(A^2+\mathit{AB}-2A\)

OAU Post UTME

\(\left(\begin{vmatrix}5&-9\\12&14\end{vmatrix}\right)\)

\(\left(\begin{vmatrix}-1&-4\\8&7\end{vmatrix}\right)\)

\(\left(\begin{vmatrix}-4&-4\\12&13\end{vmatrix}\right)\)

\(\left(\begin{vmatrix}0&-4\\-8&-6\end{vmatrix}\right)\)

\(\left(\begin{vmatrix}-7&-3\\16&14\end{vmatrix}\right)\)
