x + 2 = x - 2

I found x, twice even. EZ

[–] 0x4E4F@sh.itjust.works 3 points 1 year ago

That is probably the most correct answer.

2 = -2, easy

I find this meme and this comment section distressing. Y’all are bad at basic algebra.

Carry on, I guess.

Subtract x from both sides of the equation. You get 2 = -2 which is incorrect and nonsensical.

I know that, but @Urist@lemmy.blahaj.zone said that most of us here are bad at basic algebra. Not that I'm great at it (I had an 8 average in all 4 maths in uni), but I do believe that most of us here were correct. This is unsolvable using classic algebra.

Right there:

Clearly X= |2> + |-2> πŸ˜…

⬆️ this poster didn't normalize their linear combination of wave functions

Can someone smart explain it to dumb me

[–] odium@programming.dev 2 points 1 year ago* (last edited 1 year ago) (1 children)

Explanation: How did they get from

x + 2 = x - 2

to

(x+2)(x-2)=0?

That's not a valid step.

[–] jerkface@lemmy.ca 1 points 2 months ago

It's also necessary for x to be either 2 or -2 for the equation to have a value of zero.

[–] 0x4E4F@sh.itjust.works 0 points 1 year ago (3 children)

Almost everything is wrong in his answer.

The correct answer is, it's unsolvable.

X + 2 = X - 2

X - X = - 2 - 2

0 = - 4

[–] olsonexi@lemmy.wtf 2 points 1 year ago

The real correct answer is that it only works mod 4

[–] SpaceNoodle@lemmy.world 1 points 1 year ago

Only the first step is wrong.
