Let A and B be 2x2 matrices over the real field. Let det A and det B denote the determinants of the matrices A and Brespectively. Then which one of the following is true ? 1) det(A + B)+det(A B) =2 det A + 2 det B det(4 + B)-det(4-B)=2det A -2 det B det(A + B)+ det(A - B)=2det A - 2 det B 2) 3) (4) det(A + B)- det(A- B)=2det A +2det BB
