... NO, that is not how you use the quadratic equation. In fact that was horribly wrong. Just distribe, combine the like terms, move allvariables to one side and all constants to the other, divide, NOW you are home free on the equation. I just hate doing review math. Although now a quadratic equation is review. I'd say why not a factoring problem? you know like: x<squared>-10+100... It's a simple triinomial square... anyways of course that's not the problem because that's too easy. Someone finish this problem... I despise review.

...I think this math problem is about to create flaming. Should I post a new one?

:-_-:
Well, I never study.
And jasonguy already did most of the stuff that you said.
So what you were saying would go something like this:

x (2100/3717 x^2 + 1400/3717 x + 500/3717) = 0

Yeah, you're right.

Now what?

EDIT: Congratz on turning fourteen.

solve for x

(3x^3 - 2x^2 + 5x - 0.531) / x = 30/7

x = .87060047... something like that.

Although technically there are 3 solutions, only 1 of them is real-valued (Which I gave). To find the other 2, you would have to divide the current equation by (x-.87060047) and then use the remaining equation in the quadratic formula, which will give you 2 imaginary roots... which I'm too lazy to do.

Well, there's 3 solutions, like any 3rd-order equation. The first one is obviously 0, and the other 2 are found with a simple quadratic formula. However, you get an imaginary answer. It's (-1400/3717 +/- Sqrt (.1621298184)i)/4200/3717. Pretty simple.

Oh, that.
That's my slightly factored solution. Wait, I'll improve on it:

x/3.717 (21 x^2 + 14 x + 5) = 0
If 21 x^2 + 14 x + 5 = 0, then
x = (-14 [+/-] sqrt [196-105]) / 42

So, in my reckoning,
x = 0, -1/3 [+/-] (sqrt [91])/42

Gawd!

EDIT:
x = 0, and roughly = to -2/15 and -8/15

EDIT EDIT:
@Zhane well sorry for being an idiot.

You're uses of the quadratic formula in the improper places saddens me...

^Idiot moment

Sorrysorrysorrysorrysorrysorrysorry...

I guess
x/3.717 (21 x^2 + 14 x + 5) = 0
should have been
x/3.717 (21 x^2 + 14 x + 5) = 1
This happens to me too much.
FFUUUUUUUUUUUUUU-

How did you do it?

This is basic basic basic stuff, anyone who passed 6th grade should easily, no anyone who passed 5th grade should easily do this. It's my birthday, I'm not even going to get anything and I am pissed so, II refuse to solve it on account of two things. A. I'm having a very bad day B. It's my birthday.

Well, you could just leave it to the next unfortunate soul who comes across this thread.

EDIT: Could you please post another question? I'm stupid and can't solve this one. Just to resurrect this interesting topic.
