... Example: Test P = x3 + x + 1 for reducibility, in F2 [x]. Since (deg P )/2 = 3/2, we need only attempt division by polynomials D of degree 1 ≤ d ≤ 3/2. Since degree must be an integer, we need only consider linear (monic) polynomials D. To enumerate these, we have only a choice of constant coefficie ...

So, in the above example, R xx , appearing to the right of the p × 1 column vector rxy , must have p rows, and since it appears below the 1× p row vector ry′x , it ...

... Define bj to be the column bj = (a1,j , a2,j , . . . , ak,j )T . By linearity of determinants, det(B + iC) is the sum of 2k determinants of matrices M with dimensions k × k, where in column j we can choose to place either bj or i(−1)j+1 b2k+1−j . Given any determinant of this form, we can convert it ...
