1. The problem statement, all variables and given/known data Hello, I am stuck on this particular question for my homework. It is a 4x4 Matrix that consists of a b b b b a b b b b a b b b b b 3. The attempt at a solution My approach has been to factor out the a to give the first row of 1 b b b and then use that to make the first column consist of 1 0 0 0 and so i can then do the cofactor expansion and reduce it to a 3x3 matrix. but after that step, it gets extremely tedious and i believe that the approach must be wrong. Can anyone point out a simpler approach to this question or was I on the right track and just have to endure the tedious algebra?
