Expand this equation.Originally Posted by Richie_B
I agree, the understanding of them isn't too bad but proving them is a pain. Pythagoras' theorem is very easy to understand but the proof is way more complicated. Even the application of it was too much for this guy:
I wish I could do what he did for every algebra Q I do but finding 5cm in that one isn't hard at all. (Anyway, I think they phrase it "Solve for x" now instead of "Find x")

I don't like proving things, and I don't like showing my work. If I ever get points off on my homework, it's because I forget to show work.

Oh hey.
(a+b)^n
a^n + ab^n + ab^n + b^n
a^n + 2ab^n + b^n
Would that be correct?

I don't know the equivalent for whatever country your in, but I'm in 3rd year in Ireland so I'm guessing that's 9th grade in America. (Someone enlighten me on this please and if it helps I'm 15 going on 16) What I'm trying to say is what does the ^ stand for? Different symbols might be used in different places.

The answer is given in the original post
(a+b)^n
(a__+__b)^n
(_a___+___b_)^n
(_a____+____b_)_^_n
(__a_____+_____b__)__^__n

(To avoid a flaming from the girls on the forums I thought that one wasn't funny in the slightest bit. *cough, cough*)

If a truth is true, and a lie is false, wouldn't that make the lie true?
Like this.
2x2=4
(-2)x(-2)= 4
So this is a negative-times-a-negative-type situation.
Yes. I get straight A's in Algebra.

But a negative number is not a "false number." Positive numbers are to the right of zero on the number line and negative numbers are merely the numbers to left. You can't really equate negative numbers with "lies." They are true numbers. Originally Posted by Montros

I don't like that one equation. Since it says time AND money, it should be addition. If it was multiplication, it would be prostitution (money * time).
So here's the revised equation:
Women = Time + Money
Women = Money + Money
Women = sqrt (Evil) + sqrt (Evil)
Women = 2 sqrt Evil
sqrt: square root
