Everything you ever learned in math was a lie.

Given:  a = b

a2 = ab
a2-b2 = ab-b2
(a+b)(a-b) = b(a-b)
(a+b) = b
a+a = a
2a = a
2=1

Bam.

Very nice, I see what you did there

Extra points to anyone but mags who can tell me, without looking it up, where this equation is mathematically flawed.

Pyrgusfinn

it isn't...

I could be wrong.

Well, if a and b are equal, then a minus b would be zero, which, when you get into the multiplication and division, kind of makes the entire thing invalid.

Yup yup equation 4 blows the whole thing... Fun way to make people learn about dividing by zero though XD

Stay in school, kids.

Pyrgusfinn

Dang.  Yeah. That was my second guess.

Nothing is true.
Everything is permitted.

Must...avoid...demonstrate the finding of the x-intercept of a line using the Quadratic Formula...! :P



Advanceshipping and Rion had better be Chuck Norris approved.

Please, demonstrate.

MagmarFire

Well, if you're going to twist my arm...

y = 2x + 1
x = (-2 +- ( 4 - 4(0)1 )^.5 ) / (2(0))
2x0 = -2 +- ( 4 - 4(0) )^.5
2x0 + 2 = +- ( 4 - 4(0) )^.5
4x^2 * 0^2 + 8x0 + 4 = +- 4 - 4(0)
4x^2 * 0^2 + 8x0 = -4(0)
4x^2 * 0 + 8x = -4
8x = -4
x = -1/2

...Hey, as long as Xion is with Riku, I don't care. ^w^
