OK

Brand-new teaser.

Credible. Fitting. Challenging.

How many comments?

Any bets?

I'll say ..................... fewer than five.

(not, of course, counting this one).

(that way I can't be accused of "influencing" the results) ....

So, you can lower your finger (the one that's poised over the "offensive" button).

Oh ... you folks are so much FUN !!!!!!!

Very simple. It would have benefitted from a story to add some fun.

Sorry, Ghosty ......

Should have had higher rankings and ....

FIFTY !!!!!!!!!!!!!!!!!!!!

... comments.

But ..... everybody sez the reason is because I ... I ... I ... I... (as in ME) is here.

"Scaring" everybody off.

Do you believe that?

WHAT a bunch of C * * P.

There are other reasons why participation is so low, and we had better find them out and correct them or .....................

Braingle is DEAD DEAD DEAD

Here I am ...

your NAKED "protest" ... "ant" ....

(what did you expect .... hmmmmm ??)

Perhaps an explanation would help.

I am a protestant (protest ... er) concerning the condition and health of Braingle. I protest about it, a LOT.

I am "naked" as in .... "devoid" ... (without, don't have, missing, etc.)

of defences or friends.

I'm doing it all by myself. Not a SINGLE other Braingle participant has "stepped up" to assist me.

But .... guess what?

I expected that.

Because a person in a "state of denial" will often "deny" that the "denial" even exists.'

Look in a mirror (some of you) ... if you want to see one.

Easy enough for Joe to solve it.

the given answer is easy. But did anyone find the other answer?

Joe can also be 1.

1 + 3 = 4
1 - 3 = -2
(-2) ^ 2 = 4

Simple to see when you set it up algebraically.

x is Joe's age.

(x - 3)^2 = x + 3

x^2 - 6x + 9 = x + 3 (expand left side)

x^2 - 7x + 6 = 0 (subtract right side from left side)

0 = (x - 6)(x - 1) (factor left side, and reverse)

The two solutions to zero the right side, forming a true statement are 6 and 1.

Excellent analysis & explanation ... eighssee ...

WELL DONE !!!!!

The way the teaser is phrased it says square root which is positive by definition. Therefore 1 is not an additional answer since sqrt(4) = 2 (not -2).
