Okay, I need to find the limit of x^3-8/x-2. I know I have to factor the top into something that will give me an x-2 so that i can cancel. The only problem is i dont know how to factor the difference of perfect cubes. So please help!

behind one another. Ohm's law states that current and voltage are proportional. So technically AC circuits do not obey Ohm's law, correct? Thanks all.

I was looking for a list of common compounds using only Carbon, Nitrogen, Oxygen, and/or Hydrogen, for education/game purposes. Once I have the names, I can find out the details, but going over every possibility would be impossible.

The largest size I was thinking of NH4N03- Ammonium Nitrate, and C2H60- Ethanol.
