How do you factor x-5x^3-6x^3? Thanks!

Factoring
Can you show me how to factor x-5x^2-6x^3, and why each step is done? I'm not sure how to factor something where the x is in front instead of the highest power, and something with both a ^2 and ^3 variable. Thanks!

Why does 5x/6x^2 become 5/6x? How did x-x^2 become an x on the bottom? Thanks!

How do you factor an x^3 as in x^3+5x^2+6? Is there a general rule you can follow?

A few questions on simplifying rational expressions... 1). 15x^2/10x this simplifies to 3x^2/2 according to my book. But I would think it should be 3/2x since x^2-x=x. Why not? 2). Simplify 3xy/xy+x. How come the (xy)'s don't cancel so you are left with 3/x? 3). Can yo...

Dividing Rational Expressions
x^3-8/x^2-4 divided by (x^2+2x+4)/(x^3+8). This becomes ((x-2)(x^2+2x+4)/(x+2)(x-2) times ((x+2)(x^2-2x+4))/(x^2+2x+4). I understand that (x-2)(x^2+2x+4)=(x^3-8) when I distribute it, however, if I didn't have the help of my book, I'd have no clue how to come up with t...
