That's funny, but given the service offered some basic math isn't unreasonable.

I got:

Find the least real zero of the polynomial:
p(x)=(x+4)(x-1)(x-5)(x+3)(x-0)

But each of the zeros of that polynomial are just as real as all of the others. I'm confused now.

Well, I don't know. It's got to go up against this one.

[andrewducker]

That's fantastic!

There are also imaginary zeros. It would take an age to write out the solution using html, however, there is an explanation here which should explain it, albeit using a different function.

Oh Jesus. I hadn't seen that, but it's so true!

They're called "captcha"s?

Now: go translate the first twenty lines of Beowulf, and prove to me that *you're* all human.

A: No.

I am human as I am too lazy to be fucked with it.
