Hey guys. I'm looking for someone to do a proof. Well, actually several proofs, but we'll start with something easy (Not easy for me, though. Why? Maybe I'm stupid.) Here's the thing. Someday in the future, I would like to be super awesome at proof writing, and I've been studying the method of many proofs. Pythagoras proved his theorem geometrically with a smaller square insribed in a larger square, with the vertices of the smaller square lying in the four respective sides of the larger square. Simple, yet genious. Riemann, with his rectangles, summing them together, showed that the area under a curve could be approximated to any degree of accuracy. L'hopital, taught us that indeterminate forms were nothing to be afraid of. These people all have something in common. They were able to solve problems. Now I'm not pretending to know how these people thought, but I believe that they're approach to these daunting tasks were not only similar, but EASY.

In my opinion, I think it goes like this:

1) most problems start with a different problem. 'Man, if I could just solve this quadratic equation, that would be great!'

2)Identifying the problem with the problem. 'Why can't I solve this thing?! I shouldn't have to sit here for 2 freakin weeks testing all of the factors of of these enormous coefficients!'

3)The quest begins. 'O.K. There's got to be an easier way.'

4)Stating the problem in general terms. 'Well, I'm gonna state this thing in general terms, because I want this to work for all quadratics. I Know that all second degree equations can be written like this: $\displaystyle ax^2+bx+c=0$'

5)Racking the brain. 'I've been working on this thing for 4 months. Maybe I should just set myself on fire, wrap a bag around my head, take some pills and jump off of a bridge.'

6) A coulpe of teases. ' Oh my God! I've got it! Oh. Wait. No I don't. Stupid! stupid! stupid!.'

7)The eureka. 'Oh! What if I..... That's IT!!! The trinomial square! I'll build a simple, stupid, little trinomial square!'

8) The final proof. 'OK, let's see here......

$\displaystyle ax^2+bx+c=0$

$\displaystyle ax^2+bx=-c$

$\displaystyle x^2+\frac{b}{a}x=-\frac{c}{a}$

Now... Ha Ha Ha. I gotcha ya little bastard! You don't stand a chance before the great and powerful trinomial square.'

$\displaystyle x^2+\frac{b}{a}x+(\frac{b}{2a})^2=-\frac{c}{a}+(\frac{b}{2a})^2$

And now for the good stuff.

$\displaystyle (x+\frac{b}{2a})^2=-\frac{c}{a}+\frac{b^2}{4a^2}$

$\displaystyle (x+\frac{b}{2a})^2=\frac{b^2-4ac}{4a^2}$

$\displaystyle x=\frac{-b\pm{\sqrt{b^2-4ac}}}{2a}$

8) The dance. Whoooooooooooo!!!!!!

9)The Ego.

And that's how it goes. I've given this a lot of thought. Think about Old Isaac Newton, and the apple. Sounds like the eureka to me.

Any way, let's start with something simple.

The sum of cubes. $\displaystyle x^3+a^3=x^2-ax+a^2$

If you don't like this one. pick one. I just want to study your structure and method.

I CHALLENGE YOU ALL!!! DO A PROOF IF YOU DARE!

I'll submit one myself on this thread. Give me a minute though.
