If you wanted to look for fossils in your own backyard, or just ancient artifacts, etc. how deep would you have to remove the top layers of topsoil and clays or sandy dirt before reaching a stable zone that is immune to erosion? And how do you date it, for your specific geographic area? Are there specific depths or signs to look for when reaching a certain depth? Specifically in northern Virginia, USA near Occoquan river.

I'm doing a science project I'm nearly done except I have to do the classification and types of igneous rock, I did the types, but I still need the classification, my sources on the iternet are telling me opposing things, and my textbook doesn't say it anywhere. If you could please tell me I don't need descriptions or anything just the classification I could do the rest myself, I however think it is extrusive and intrusive, is that right?

Gosh Algebra was so long ago. I just saw a problem and figured it out but cant figure out how to get binomials to a problem.

How do you take 2x^2 - x - 6 and get it into (2x + 3) (x-2)

I know how to FOIL and get it into 2x^2 -x -6, but I cant reverse.

Thanks guys... no rude comments please!
