What is the cross product of (1, 2, 1)^{T} with (0, -1, 2)^{T} ?

To evaluate this,
find the cofactors of **i**, **j**, **k** in the top row.
In the picture, the cofactors are circled in red.
The cofactor for **i**, for instance, is the
elements of rows 2 and 3 other than those in column i.

To evaluate a cofactor, multiply the two elements on the main diagonal,
subtract from that the product of the two elements on the other diagonal.
For example,
for the cofactor of **i** this is
2×2 - 1×(-1) = 2 + 1 = 5

What is the cross product of (0, -1, 2)^{T} with (1, 2, 1)^{T} ?
Fill in the blanks.
