Tuesday's farm riddle

[L107ANGEL]

Listen to the soothing tone of my voice..........you will be just fine on your test......you will not freak out and will get an A.

Oh snap!

I wish someone would use that on me.

or my kids! lol

Sorry, Boxer. my fiance came over for lunch. I'm going to take this to PM so I don't bore the other riddlers. Just give me a few minutes to type it all out.

 

[Loubon]

Here....I worked it out for you.....

 

[Mnementh]

Rats... I just sent her that long explanation and she signed off...

 

[firstmickey]

Darn it brat...you should have posted it here!

It was gonna be my Halloween riddle tomorrow!


Lou....get a life or somethin!

 

[Mnementh]

I still have a copy of the message in my sent PMs. Want me to post it?

 

[Mnementh]

What the hell, I'll post it anyway because I'm about to sign off and read and I don't feel like waiting for an answer. Let's hope it gets us closer to the hooty rather than killing the riddle.

99.9% of the time, the answer will be in the form (coefficient * a^2 +/- coefficient * b^2) * (coefficient * a +/- coefficient * b)

A good way to start out is to make the coefficients in the second parentheses the same as the coefficients of the first two terms of the equation. For example, the first two terms in your equation are 10a^3 + 4a^2b, so make the coefficient of a be 10 and the coefficient of b be 4. So far, we have:

(coefficient * a^2 +/- coefficient *b^2) * (10a +/- 4b)

Next, pretend the coefficents of a^2 and b^2 are 1. FOIL like you normally would.

You would come out with 10a^3 +/- 4ab^2 +/- 10ab^2 +/- 4b^3. The multiplication with a^2 came out correct, but the multiplication with b^2 didn't, so the coefficient of b^2 isn't 1. You just have to figure out what it is, which is just simple arithmetic that I'm sure you can figure out. The coefficient of b^2 comes out to be 3/2.

Now, the equation should look like (a^2 +/- 3/2b^2) * (10a +/- 4b)

Only thing left to do is to determine whether the signs are pluses or minuses. The easiest way to do this is to just guess and check. There are only four possible combinations, so it shouldn't take long.

In the end, you should come out with (a^2 - 3/2b^2) * (10a + 4b)

On a different topic, I noticed our teams are playing on Monday night this week. Should be an interesting matchup.

Here....I worked it out for you.....

Ooooh YOu're gonna get it!!!


and Thanks Jr! This really helps

 

[Mnementh]

Oh good. I thought you had signed off for the night and weren't going to get it until it was too late.

 

[Mnementh]

I knew math would kill the riddle... so close to a hooty, too

 

[brightspark]

Morning all! So near yet so far from a hooty! Love the maths!

 

[MadScouser]

Can we sneak a hooty sparky ?

 

[brightspark]

Well Mr Scouse as we are on the boards at this unearthly hour, I don't see why not... unless of course there are any lurkers out there....

 

[MadScouser]

I doubt it...

 

[brightspark]

WOOOOOOHOOOOOOTY

It's gonna be a good day in the Sparky/Scouser household!
