If {A}=[\table 1 , 2 , 3 ; 4 , 3 , 2 ; 3 , 4 , 5] then( {A}+ {A}^{ {T}})( {A}- {A}^{ {T}})=

Correct Answer is : 4[32−330−332−3]

4[\table 3 , 2 , -3 ; 3 , 0 , -3 ; 3 , 2 , -3]

\left[\begin{array}{ccc}12 & 8 & 12 \ 12 & 0 & 12 \ 12 & 8 & 12]\end{array}

4[\table 3 , -2 , -3 ; 3 , 0 , -3 ; 3 , -2 , -3]

\left[\begin{array}{ccc}-12 & 8 & 12 \ -12 & 0 & 12 \ -12 & 8 & 12]\end{array}
