OH SHIT
YOU GUYS BLOWING UP YET?
2a = a would be a/2
a = a/2 Still kinda the same thing, but with that oversight, if I looked close enough I could figure out where it went completely wrong.
The fifth step is fucked up, someone did something to fuck it up.

Substitution isn't calculus. It's algebra.
People, there's nothing wrong with it. It's a trick problem when given that a=b. One can be substituted for the other, which makes the problem basically impossible.

I don't know how they got from the fourth step to the fifth step. It amazes me.
(a+b)(a-b) = b(a-b)
a2-b2 = ab-bb
thats the real fourth and fifth step.

It says (a+b)(a-b)
but that's 0. that's the error

a=b remember? It really says 0=0

Then:
a
2-b
2 = ab-bb
aa-bb = ab-bb
aa = ab
aa-a = ab-a
a = b

Yeah, and if you're saying that it's dividing by zero at all, you really need to go back to math.
Maths my only subject in school that I enjoy.

good beef. thumbup;
Okay, I did it all, the fifth step is fixed, but one through four are the originals.
a = b
a2 = ab
a2-b2 = ab-2
(a+b)(a-b) = b(a-b)
a2-b2 = ab-bb
aa-bb = ab-bb
aa = ab
aa-a = ab-a
a = b

but that's 0. that's the error
Duh. That's the problem that arises with setting the only two variables you have equal to each other.
c=d
c-d=0
Of course, that's correct, since they're the same thing.
c
2-d
2=0
Naturally, that's also true. But of course, it can be factored (or unfactored, whatever)...
(c-d)(c+d)=0
That being said...
c-d=c+d
Still makes sense, yes. If we kept going, we'd get...
2d=0
Which is of course, true. The problem is that c=d, so the following must also be true...
c-c=c+c
The text should say that substitution is what fucks things up, not calculus. There's no calculus in that entire problem, unless my algebra teacher was lying of course. That's all too possible.

Cool, I made an error in that last post I made. Oh well. Either way, the point I'm trying to make is that you can't set those variables equal to each other and expect to be able to get a logical answer out of substitution.
Oh in the fourth to fifth step they just minus a-b and make it disappear (on the right side) which is logical since a=b, but if you subtracted that right side, you'd have to minus a-b from the left side, and simplify all of it, at least I think so. Thats the error but I'm not sure how to explain it.

It's a legal move, it just doesn't give you a legal answer. Just one of the many times something like that can happen.

You're
supposed to be able to, but the equality makes for it being impossible to substitute the way this person did.

I remember my teacher saying "whatever you do to one side, you must do to the other" though, which if what he says also is used in this case, would make this true and would make it so one doesn't equal two.
a = b
a
2 = ab
a
2-b
2 = ab-
2(a+b)(a-b) = b(a-b)
(a+b)(0) = b(0)
0 = 0
Thats how it should be solved I think. Although I'm sick of this problem now caterpie;
