Can someone walk me through this problem?
1/x - 1/(x+1) = 3

I started by multiplying the whole equation by x(x+1), so I could find the common denominator. I got:
x + 1 - x = 3x(x+1) or
1 = 3x^2 + 3x

Now I'm stuck. Did I do this first part right, and if so, where do I take it from here?

A mathematical answer is what I need. Something like you need 3 noncollinear points to make a plane. Thanks

The distance to Alpha Centaurai is 6.0 x 10^16 METERS. If space ship Fang can travel 8.0 x 10^7 KILOMETERS in 2.0 years, how many years does it take to reach Alpha Centaurai?

Sorry For the Caps

Originally people answer to this question was 1.5 x 10^9, but i need to know if it is right because i am dealing with Meters and Kilometers. And i think they answered the question assuming both numbers were meters.

I found a nest in my garage while cleaning it out. The nest is about the size of a hand and is made of twigs and some peices of plastic. It had tiny, white, (cracked) eggs in it that were the size of a pinky finger nail. I was wondering what could have made the nest.
