I'm blanking here on one of the most simplest math question... How does (x^2)/(x^2+1) simplifies to x - (1/x^2+1)? Help please...?

It doesn't. $\displaystyle \frac{x^2}{x^2 + 1} = \frac{(x^2 + 1) - 1}{x^2 + 1} = \frac{x^2 + 1}{x^2 + 1} - \frac{1}{x^2 + 1} = 1 - \frac{1}{x^2 + 1}$.
oh...no wonder it didn't make sense. that's for clarifying!
