WebThe determinant of a matrix is a sum of products of its entries. In particular, if these entries are polynomials in , then the determinant itself is a polynomial in . It is often of interest to determine which values of make the determinant zero, so it is very useful if the determinant is given in factored form. Theorem 3.1.2 can help. WebSolution Conditions when the determinant can be zero: There are three conditions, where the determinant can be zero. 1. If the complete row of a matrix is zero. Example: 0 0 0 1 1 2 2 3 1 etc. 2. If any row or column of a matrix is the constant multiple of another row or column. Example: 1 2 3 2 4 4 1 2 5 etc. 3.
