That is probably the most correct answer.
2 = -2, easy
I find this meme and this comment section distressing. Yβall are bad at basic algebra.
Carry on, I guess.
Do enlighten us.
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.
Source: trust me bro
Right there:
Clearly X= |2> + |-2> π
β¬οΈ this poster didn't normalize their linear combination of wave functions
Can someone smart explain it to dumb me
Explanation: How did they get from
x + 2 = x - 2
to
(x+2)(x-2)=0?
That's not a valid step.
It's also necessary for x to be either 2 or -2 for the equation to have a value of zero.
Almost everything is wrong in his answer.
The correct answer is, it's unsolvable.
X + 2 = X - 2
X - X = - 2 - 2
0 = - 4
The real correct answer is that it only works mod 4
Only the first step is wrong.
