Show that if each element of one row (or column) of a determinant is the sum of two terms, the determinant can be written as a sum of two determinants; for example, a 11 a 12 + b 12 a 13 a 21 a 22 + b 22 a 23 a 31 a 32 + b 32 a 33 = a 11 a 12 a 13 a 21 a 22 a 23 a 31 a 32 a 33 + a 11 b 12 a 13 a 21 b 22 a 23 a 31 b 32 a 33 Use this result to verify Fact 4b of Section 3.
