Find the values of a, b, c and d such that (pmatrix) 5&a b&0 (pmatrix)-2(pmatrix) c&
If the determinant of a matrix is not zero, then the rank of the matrix is equal to the order of the matrix. This can be used as a shortcut. But this shortcut does not work when the determinant is 0. In this case, we have to use either minors, Echelon form, or normal form to...
