I need to know if you use mediums/psychics in your research? If you do, why? I have been doing this since 1999 and can see no reason for involving this in an actual investigation. What would they bring to the table so to speak that coud ever be evaluated by an objective researcher? I call myself a skeptical believer simply because I have no absolute proof of anything other than my few pics I elected to keep. None of which I label as a ghost or spirit. I call them simply......interesting pics. Out of thousands of pics there are maybe 20 and of those two are orbs, only to show contrast in light sources and anomalies. I have never kept an EVP simply because none were clear and audible. And I have only kept about 5 minutes of video where I caught something I am still trying to figure out. That in almost 8 years of searching. So I am much harder on evidence than your normal "ghost hunter". So if you please will answer my first questions and your experience level, I would like to know.

This section is well hidden I asked this same question in Society and culture/mytholgy & Lore and they told me to ask it here. So, have you? I have and it was a good apparation, It was a jet black apparation and I saw it in the dark. It was just standing in my living room motionless and about 6' tall. Haven't seen it since. That was about 4 years ago. Also I've seen several cats in black wonder apparations.

please help! i hate listing zeroes and stuff and i have actually tried but i dont get it

For the following polynomials list the possible rational zeros. (Do not find the zeros!)

P(x) = x^5 + 3x^3 + 2x - 6

P(x) = 3x^4 + x^3 + 2x^2 - 2

P(x) = 2x^5 + 3x^4 + 2x^2 - 2
