The inverse of matrix \(P=\left[\begin{array}{ll}10&-2\\ -5&1\end{array}\right]\) is

\(\left[\begin{array}{ll}1&2\\ 5&10\end{array}\right]\) \(\frac{1}{10}\left[\begin{array}{ll}1&-2\\ -5&10\end{array}\right]\) Inverse does not exist \(\left[\begin{array}{ll}10&2\\ 5&1\end{array}\right]\)

Inverse does not exist

\(\det(P)=0\)
