    I want a easy formula for integration A2

    That's the formula though. You're gonna have to practice to get it, I think. Not so good with it myself.

    Take the x common. You'll get (x)(1 - x^2) < 0. That makes two roots, (x) < 0 and (1 - x^2) < 0. The first one's solved in itself, for the second one you just go about it as a regular equation; 1 < x^2 and then under-root both the sides and you'll get x > 1. I think I might be wrong here though...
