Homework Statement
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
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?
