(x^3-3x^2+2x-1)dx / (x^2-4x+4)

I came up with: (x2)(x2)

But, Daaaad!
I'll do it tomorrow!

You're so vain,
You probably think this sig is about you.

Um, why is there a random differential?

And why are you claiming that 3 - 2 = 2?

It ain't homework.

Here's the pic where I got the equation...

In other words, mathematical BS (at least as far as I can discern)

@DreamwaIker or am I missing something <_<

Yeah I got nothing, sounds like just whoever wrote that was trolling

I want to see your working for how you got your answer.

Me? I just used an online calculator. I'm not a good math person. =\

Well, Im assuming whoever wrote that wanted you to take the derivative of the numerator, simplify that, simplify the denominator, and then cancel out stuff, then solve for x, but not only is the derivative written wrong, you cant really solve for x since there is only one equation and two unknowns, (x and Pin).

I was thinking that too actually.

Before we even get to the nonsense of the incomplete derivative notation and the fact that no 4 digit PIN would come from that...

It's not even an equation.

No because this isn't an equation.

Even if you were taking the derivative of the numerator then finding the roots it would still make no sense.
