Ok..

I'm not able to do this question.How can I reduced it into RREF without knowing the elements of row3...? Its confusing me a lot.

Question a) For each of the following matrices explain why the matrix is not invertible. i)[2,0,0_0,0,0_9,3,0] ii)[3,4,-6_7,2,1_-6,-812] iii)[5,-2,15_1,-4,3_2,1,6] b) Suppose A is an n×n matrix with the property that the equation Ax = 0 has only the trivial solution. Without using the...
