In summary, solving for u is a problem that can be solved by anyone, not just scientists. It requires some math knowledge and problem-solving skills, but it is not limited to a specific group. While some problems may be more difficult than others, most can be solved with patience and persistence. To check if you're on the right track, double-check your work and compare it to examples. Common mistakes when solving for u include not following the order of operations, making calculation errors, and not checking your work. It's essential to be careful and use the appropriate method or formula for the problem at hand.

I've got something like
[tex] u + LuL^T = v [/tex]
and I want to write it like
[tex] u = B_1 v B_2 [/tex]
for some B_1 and B_2. Assume L is nice and invertible.

Is this impossible or am I just not seeing it? This is making me feel dumb. Too much programming and its getting late.

I assume all the letters you wrote are n x n matrices...

Try multiplicating the first u on the left by LL^-1 and on the right by (LL^-1)^T, then collect terms...
