the determinant function is multiplicative which means det(AB) =det(A)*det(B)
so first i suggest to add -2I to both sides then take the det
BXA^2 = -2I
can you continue ?
hello, this look rather simple, but I struggle, I need some help, or at least a final answer so I can check myself....thank you
A and B are 5X5 matrices. it is known that:
det(A)=2
det(B)=-3
X is a square matrix so BXA^2 + 2I = 0
(multiplication of B, X and the square of A, plus twice the identity matrix)
what is det(X) ?
