16 - 36 = 25 - 45
Both result in -20, so they're equivalent, right?

(16 - 36) + 81/4 = (25 - 45) + 81/4
Since they're both equivalent, let's add 81/4 to each side

a^2 - 2*a*b + b^2 = (a - b)^2

or

4^2 - 2*4*(9/2) + (9/2)^2 = 5^2 - 2*5*(9/2) + (9/2)^2
(16 - 36 + 81/14 = 25 - 45 + 81/4)

4 - 9/2 = 5 - 9/2
Performed square root and subtraction from each side

4 = 5
Removed extraneous data (9/2) from each side

Therefore:

2+2 = 5

... right or wrong?

a^2 - 2*a*b + b^2 = (a - b)^2

That would be a brand new kind of math than I never learned.

Odysseus · 01-12-2011, 04:48 PM

(4 - 9/2)^2=(5 - 9/2)^2
|4 - 9/2|=|5 - 9/2|
4 - 9/2=+\-(5 - 9/2)
4 - 9/2 = -5 + 9/2
4 + 5 = 9/2 + 9/2
9 = 9
2 + 2 = 4 !!!

i could be wrong, but from my trig days, i believe this is the pythagorean formula.

Some dumb ass college that told me to solve the problem by isolating "a" and "b" and
defining "a" in terms of "b" or "b" in terms of "a" and then plugging in either a value for "a" or "b" and then solving the equation for the other variable.

Yeah, wish I could get my money back for that course.

Oh yeah,

Like a^2 + b^2 = c^2

It's like a^2 is one side of the triangle and b^2 is another side and c^2 is the hypotenuse.

what happens if you have value 7=c^2 and try to solve for c?

Odysseus · 01-12-2011, 05:10 PM

2+2=5 or 2*2=5 - this equates to only when you go to the bank to take credit! ;)

a^2 - 2*a*b + b^2 = (a - b)^2

I got this when I tried that :

(a - b)^2 = (a - b)*(a - b) = a(a - b) - b(a - b) = (a^2 - ab) - (ab - b^2) = a^2 - 2ab - b^2

Oldie but a goodie.

Much simpler version with a=2 b=1 and easier to follow.

I didn't check it, but I'm 99% sure you introduced an irrelevant root.

No use making a joke at this point as Americans don't Root!

CLUE

LET X = -2
X^2 = 4
X = SQRT(4)
X = 2

2 = -2

justfreemovies · 01-13-2011, 02:45 AM

hold up let me bust out my abacus..... ticking fills the room

cam_girls · 01-13-2011, 03:06 AM

So you've got

let
a^2 - 2ab + b^2 = c^2 -2cd + d^2

therefore
(a - b)^2 = (c - d)^2

therefore
(a - b) = (c - d)

let a = 1, b = 2, c =4, d = 3

(1 - 2)^2 = (4 - 3)^2

1 = 1

Even though (1 - 2) =/= (4 - 3)

so X^2 = Y^2
-/-> X = Y
(equal squares does not imply equal values)

darksoul · 01-13-2011, 03:12 AM

Heres one problem thats elementary and uses no tricks.
1/3 = 0.(3) (0.(3) means 0 followed by an infinite number of 3s 0.333333333333...)

1/3 + 1/3 + 1/3 = 3/3 = 1

0.(3) + 0.(3) + 0.(3) = 0.(9)

results:

1 = 0.(9) !

cam_girls · 01-13-2011, 03:36 AM

There is no possible number between 0.999999... and 1

so they must be equal.

While the first 8 match, the 9th is made so your logic works because 9/9 =1 not 0.(9) because you say so.
