Yet what are all such gaieties to me
  Whose thoughts are full of indices and surds?

 x2 + 7x + 53

that is not the answer

no pizza for you

a high school buddy and i cut school and went to the Gaiety Burlesque. Where did you guys go when the algebra teacher taught everybody else how to solve this crap?

Phroso said...

Your Dudeness,
The answer in mathematical terms is "i".
You must come up with a number when squared and multiplied 7 is equal to -49.33333333333. This cannot be done since the number must be a negative number. But when you square a negative number it yields a positive number.
Here's the progression.
X=0 yields 0
-1 = -6
-2 = -10
-3 = -12
-4 = -12
-5 = -10
-6 = -6
-7 = 0
-8 = +8
-9 = +18
-10 = +30
Thus X = i (imaginary).

Okay, I apologize ... you didn't cut school and miss that algebra class.

Except that you took algebra around 1550 A.D., and that was the state-of-the-art leading-edge answer to this kind of thing in 1550 A.D.

i is just one component of The Answer. The PizzaQ answer is way more than just i.

Phroso said...

Mathematics hasn't changed since the big bang.
Plus I wasn't even born in 1550 A.D.!
You can write an equation defining "X" but why bother if "X" doesn't exist?
MAYBE for a whole pizza it's worth the effort, but I'm too old to eat that junk. I take my meals through a straw or IV.
Gotta chase the kids off the lawn.

Okay so I just left a comment and as soon as I do there's another box that says "Leave your comment"!!! What's THAT all about?
And what ever happened to the little thingy at the end, you know when it asks you to replicate a random realimaginary word in exchange for the internet immortality of posting something on your blogish page?
Now it just asks if you're a robot. I already told you I am not a robot. And what do you have against robots. Maybe they'd like to post some evangelical message to your subscribers.

Vleeptron Dude said...

Phroso, I confess I replied to your answers with rudeness and sarcasm -- which is the ancient tradition of math teachers. I sincerely apologize.

I guess I'll give you a tiny hint. Focus on that word you used: "exist". In mathematics, existence is a lot more complicated than you seem to think it is.

"I want you to just let a wave of intolerance wash over you. I want you to let a wave of hatred wash over you. Yes, hate is good... Our goal is a Christian nation. We have a biblical duty, we are called on by God to conquer this country. We don't want equal time. We don't want pluralism." Randell Terry

You were right to use rudeness and sarcasm.
I should apologize to you - I lied about the robot thing.

Just so you know The Residents will be in town April 25, 2016 A.D.
See you there.

Vleeptron Dude said...

1. Hey Anonymous -- you mean The Residents who wear giant eyeballs instead of their heads? And which town? I suppose I can figure this out. But your assistance would be appreciated.

2. Phroso --

I'm mildly enjoying the detours your comments are shoving me into.

a. Actually there's an ancient "flavor" to teaching math. It's supposed to be unpleasant, and certainly supposed to be annoyingly, frustratingly hard. One reason, I suspect, is that that's the best and fastest way to shake mediocre or bad students out of math.

Math isn't reserved just for natural geniuses and savants.

But it IS reserved for people with a violent determination to master this crap. 99 percent of students who get a D or an F in calculus never go back to math again.

But 1 percent bundle up their embarrassment and humiliation and sign up for the same course next semester -- even if it's taught by the same person who gave them the F. (And they do much better the second time. And then sign up for the next harder math course.)

Talking Barbie was absolutely right when she said: "Math is hard!"

b. Mathematical Truth indeed is unchanged and eternal through time and (we believe) everywhere in the universe(s).

Human discovery of mathematical Truth does change and expand constantly. And this PizzaQ is a very famous example of New Discoveries in mathematics.

c. My Robot Test was an annoyance the first time. But after I passed and it concluded I wasn't a Robot, every time since then I just click the box, and quickly pass. It remembers the Vleeptron Dude passed the first CAPTCHA (or however you spell it.)

Vleeptron Dude said...

Okay that wasn't hard.

I could do that.
And everybody should do that.

DJ R Superluminal said...

No Bob simply isolate the x and solve for the rest of the equation.

Vleeptron Dude said...

That's not the answer. That's a fine PLAN to find the answer. But it's not the answer. What's the answer? x = ?

Did EVERYBODY cut school and go to the Gaiety Burlesque when the algebra teacher showed how to do this?

-7/2 ± (i * √1335)/6

Vleeptron Dude said...

First, Vleeptron congratulates the sole respondent who did not cut that algebra class to go to the burlesque house, and who had the skill and daring to venture beyond "there is no answer, the answer doesn't exist."

HOWEVER ... I (and Mrs. Lafferty the Algebra Teacher) aren't satisfied.

1. Vleeptron doesn't want any denominators in these two fractions.

2. Vleeptron doesn't want any square root signs.

In other words, simplify your expression and let me know what you cook up.

But wow! SOMEBODY believes there's MEANING to the square root of a negative number! What a concept!
