If A=\left[\begin{array}{cc}1 & -1 \ 2 & -1]\end{array}, B=\left[\begin{array}{cc}1 & 1 \ 4 & -1]\end{array}, then (A+B)^{-1} is

Correct Answer is : [12032−12]

\left[\begin{array}{c}\\\{-1\end\frac{array}{2} , 0 ; \frac{-3}{2} , \frac{1}{2}]}

\left[\begin{array}{c}\\\{1\end\frac{array}{2} , 0 ; \frac{3}{2} , \frac{-1}{2}]}

\left[\begin{array}{c}\\\{1\end\frac{array}{2} , 0 ; \frac{-3}{2} , \frac{1}{2}]}

\left[\begin{array}{c}\\\{1\end\frac{array}{2} , 0 ; \frac{3}{2} , \frac{1}{2}]}
