The inverse of the matrix A = \(\left( {\begin{array}{*{20}{c}} 1&1&3\\ 1&3&{ - 3}\\ { - 2}&{ - 4}&{ - 4} \end{array}} \right)\) is:
1
\(\left( {\begin{array}{*{20}{c}} 3&1&{1.5}\\ { - 1.50}&{ - 0.25}&{ - 0.75}\\ { - 0.25}&{-0.25}&{ - 0.25} \end{array}} \right)\)
2
\(\left( {\begin{array}{*{20}{c}} 3&1&{1.5}\\ { - 1.25}&{ - 0.75}&{ - 0.25}\\ { - 0.25}&{-0.25}&{ - 0.25} \end{array}} \right)\)
