You've been warned.

Anyone up for some factoring of trinomials?

x² + 8x + 15

x² + 2x - 3

x² + 5x + 8

x² + 14x + 33

x² + 11x + 28

I am!

(x+3)(x+5)

(x+3)(x-1)

Don't know if this will go into two brackets. Completing the square it's (x+2.5)² +1.75

(x+11)(x+3)

(x+4)(x+7)

I was told there would be no math....

What? Ban me? Just trying to add some educational value to my usually boring threads.

Good job Emperor, now I can go grade my quizzes.

"Cough, cough" Math! I am so very bad with it! It was my worst subject

CIVITAS · May 30, 2005 3:37AM

Is it nerdy in here or is it just those guys.

(OK, I relent, it's nerdy in here.)

MadMarty · May 30, 2005 5:34AM

math suks

trozau · May 30, 2005 5:40AM

<< Don't know if this will go into two brackets. Completing the square it's (x+2.5)² +1.75 >>

or (x+2) * (x+3) + 2

This thread is OT and should be moved to the Stamp Forum at once!

Really? How did you figure that out? You must have had help.

Aethelred · May 30, 2005 6:21AM

I know OT when I see it, don't have to spell it out for me!

I see wybrit finds math boring.

counting on your toes again I see Don!!

No, I gave a pop quiz last Thursday and didn't feel like figuring out the answers.

wybrit · May 30, 2005 10:22AM

I see wybrit finds math boring.

Not really, just ajaan threads about math.

For ajaan only: name these famous equations/theorems:

c² = a² + b² - 2 a b ( cosC )

f( x ) = f( 0 ) + xf '( 0 ) + ½ x² f "( 0 ) + 1/6 x³ f "'( 0 ) + ...

If A = MPM¯¹ then A² = M P² M¯¹, A³ = M P³ M¯¹, etc

z² y" + z y' + ( z² - n² ) y = 0, assume y = f(z) and n is a constant.

(Edited to make them a little more readable and for clarification)

Translation: "I dunno!"

wybrit · May 30, 2005 10:28AM

Since ajaan is always hijacking my threads, I will do the same to him.

The first person to correctly answer all the challenge questions that ajaan could not answer wins a coin.

What coin?

wybrit · May 30, 2005 9:29PM

What coin?

That's for me to know and the winner to find out!

ajaan · May 31, 2005 6:31AM

I'll give everyone the first one. Law of cosines.

wybrit · May 31, 2005 11:54AM

Three more left. Any takers?

ajaan · June 1, 2005 3:29AM

C'mon people. I guess darksiders aren't as geeking as first thought.

#2 This is some kind of series. Taylor or Maclauren?

Steve27 · June 1, 2005 4:02AM

"Anyone up for some factoring of trinomials?"

Yes, but those are binomials!

ajaan · June 1, 2005 8:03AM

<< Yes, but those are binomials! >>

I beg to differ. Three terms = trinomial, to be more specific they are quadratic trinomials.

1jester · June 1, 2005 8:31AM

Steve, don't argue with a geeky shroom!

wybrit · June 1, 2005 9:46AM

ajaan has nailed #2! It is both a Taylor and a MacLaurin series. The latter is a specific case of the former.

ajaan · June 1, 2005 7:05PM

Anyone for equation #3 or 4?

lordmarcovan · June 2, 2005 10:38AM

I'd rather pluck out my right eye and pour Tabasco sauce in the socket, thankyouverymuch.
