Hey, /wsr/, first time poster here. I have been trying to figure

So you know a^2 + b^2 = c^2, right?

You just have to apply that properly.

A = x
B = Square root of 2
C = (x+1)

Square them all so you'd have

x^2 + 2 = (x+1)(x+1)

After you expand the bracked, you should be able to break it down to get your x's on one side and your digits on another which gives you what x is. You follow?

And since you seem to have the ability to check, x is 0.5, right? It'd be pointless to tell you this if I was wrong kek

But isn't (x + 1) * (x + 1) = x*x + 2*x*1 + 1*1 = x^2 + 2x + 1?

>>248116
Precisely.

So now you have
x2 + 2 = x2 +2x +1

Right? You follow all this without issue, right?
From that point you just work with the equation to put your x's on one side and your digits on the other. I assume you know how that works? For example
5+3=8
Can become 3=8-5
Since you take the 5 over to the other side and it becomes a minus
I'm shit at explaining this but you surely know what I mean since this is pretty basic. If you don't I can go into it further but it doesn't seem necessary

>>248117
x2 obviously meaning x^2

>>248116
Not him, but he says "expanding the brackets," which is what you just did.

He's also correct. x is 0.5 or 1/2.

>>248112
thank you very much!

I take it you understand it then? Good to see
