There are two values of a which makes determinant , A=|(1,-2,5),(2,a,-1),(0,4,2a)|=86 , then sum of these numbers is :

In the determinant, Delta = |[-2, 5, -1], [4, 7, 0], [5, -3, 1]|, the sum of the minors of elements of third row is

Delta=det[[1,2,4-1,3,04,1,0]]

" Express "A=[[3,3,-1],[-2,-2,1],[-4,-5,2]]" as the sum of a symmetric and a skew symmetric matrix."
