Hey there, having a dizzy moment here at the mo about right and left inverses. We've got the matrix B given by first row (1 3 5) and second row (2 4 6). Normally I'd just have BC=I where C is 3x2 and we have the 2x2 identity matrix. However, I'm confused about solving it because the one we solved in class was B= first row (400) and second row (050), which was like a matrix that had been reduced by Gaussian elimination or something (or maybe it was justcoincidence!)... anyhoo, am I supposed to reduce my B matrix (the first one I mentioned), or do I just shove it stright into BC=I where C is the inverse of B? I've tried just shoving it in but I'm not sure how I'm supposed to solve it with all the unknowns. We're told to find the general form of the righ inverse of the matrix B, so does this mean we can have unknowns in it or something or something instead of them? I'm so confused. Any help would be really appreciated. Thanks!
