Hi seders99,

This is a product. You don't need a common denominator.

I think what you have written is this:

$\displaystyle \frac{x^2-4}{x}\cdot \frac{3}{x-2}$

If that's not it, let me know.

Now factor the numerator in your first fraction.

$\displaystyle \frac{(x-2)(x+2)}{x} \cdot \frac{3}{x-2}$

Can you finish? - May 6th 2009, 09:06 AMseders99
ok well that makes sense!! thanks

so my answer is

__3(x+2)__

x

Correct?? - May 6th 2009, 09:11 AMmasters
