ern 3 Let A =ã(a-4) -1 2 (a -1) i) Use row operations to put A into upper triangular form using only type I and III operations [upper triangular means that A(i,j)0 whenever i >j. ii) Use i) to find the values of a for which the matrix A is singular. ii) Assuming a to be a value of the indeterminate a, by computing rref([AI) different from those listed in ii), find an explicit expression for A1 in terms
