#1 Matrix Algebra help in Off Topic

no, this is not homework

Just feeling retarded because I'm failing this simple algebra problem:

X(A+I)=I+A^-1, solve for X (they're all compatible matrices and I is the identity)
Now, I can see that the solution is A^-1, but if I try to solve by multiplying (A+I)^-1, this happens:

X=(I+A^-1)(A+I)^-1 <---edit:this was wrong
X=(I+A^-1)(I+A^-1)
X=(I+A^-1)^2 = I+2A^-1+A^-2

what am I doing wrong nerds pls help

Pretty much what I thought, I'm not the most decisive person on these issues and still am trying to figure out and understand some of these issues.

GlastryI looked everyone as well, it's not because we'r not answering something that it's not interesting ...

But nobody benefits from it. There's no meaningful discussion and everyone just answered 117 questions to no effect whatsoever.

#38 Intel CPU Security Flaw in Hardware

Damn... are you doing anything about this personally, Setsul? Besides applying the patches. Seems like there's nothing that can be done short of disabling all online banking, deleting all emails and living an offline life, but still feels pretty bad to think that all your banking data/passwords/bitcoin could be scooped up in theory.

You didn’t listen. Memes have continued into 2018 and it’s all your fault. But we can still salvage the future. Next time you’re thinking about copy/pasting a meme, remember this message, take a deep breath and stop yourself. Humanity is depending on it.
Enough is enough. It's 2018 now. We've had our fun but it's time to grow up. Let's put an end to memes and this childish copy/paste culture.
