simplifing an alegbraic equation

grapz said:
[ x + (1/x) + 1] / [ x + (1/x) + 2]

I tried to just multiply the top by x, but it seems i get the wrong answer

\(\displaystyle \L \frac{x + (1/x) + 1}{x + (1/x) + 2}\)

I would combine all terms in the numerator and denominator into single fractions, and then simplify:

= \(\displaystyle \L \frac{\frac{x}{1} + \frac{1}{x} + \frac{1}{1}}{\frac{x}{1} + \frac{1}{x} + \frac{2}{1}}\)

= \(\displaystyle \L \frac{\frac{x^2+1}{x} + \frac{1}{1}}{\frac{x^2 + 1}{x} + \frac{2}{1}}\)

= \(\displaystyle \L \frac{\frac{x^2+1 + x}{x}}{\frac{x^2 + 1 + 2x}{x}}\)

= \(\displaystyle \L \frac{x^2+1 + x}{x}\cdot\frac{x}{x^2 + 1 + 2x}\)

= \(\displaystyle \L \frac{x^2+1 + x}{x^2 + 1 + 2x}\)
