Yo fuck you .

say what? whats the beef?

[The artist formally known]

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.

[Daddy]

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.

It says (a+b)(a-b)

but that's 0.  that's the error

(a+b)(a-b) = b(a-b)
a²-b² = ab-bb

thats the real fourth and fifth step.

a=b remember?  It really says 0=0

a²-b² = ab-bb

thats the real fourth and fifth step.

Then:

a²-b² = ab-bb
aa-bb = ab-bb
aa = ab
aa-a = ab-a
a = b

a=b remember?  It really says 0=0

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.

Yeah, and if you're saying that it's dividing by zero at all, you really need to go back IN POG FORM to math.

good beef.

[The artist formally known]

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

[Samus Aran]

It says (a+b)(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.

c²-d²=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.
