Hi, welcome to the forum. Pls note it is preferred you show some your attempts with your work so we know where exactly to help.

Anyhow, here's some help with the first one.

$\displaystyle \displaystyle \frac{x-\frac{1}{x}}{1-\frac{1}{x}}$

$\displaystyle \displaystyle \frac{\frac{x^2-1}{x}}{\frac{x-1}{x}}$

$\displaystyle \displaystyle \frac{x^2-1}{x}\times \frac{x}{x-1}$

$\displaystyle \displaystyle \frac{x^2-1}{x-1}$

$\displaystyle \displaystyle \frac{(x-1)(x+1)}{x-1}$

$\displaystyle \displaystyle x+1$

Did you follow? - Oct 20th 2010, 02:02 PMphysicswannabe123
