De determinant

is te ontbinden in
precies drie factoren.
Eén ervan is   (a + b + 2).
De twee andere zijn
A.   (b − 1)(1 − a + b)
B.   (b − 1)(b −1− a)
C.   (b + 1)(b − a + 1)
D.   (b + 1)(b − a − 1)
E.   (a − b)(1 − b)
A    B    C    D    E

Factoring the determinant

one of the factors is   (a + b + 2).
The two other factors are
A.  (b−1)(1− a+b)
B.  (b−1)(b−1− a)
C.  (b+1)(b− a+1)
D.  (b+1)(b− a−1)
E.  (a− b)(1− b)
