My problem understanding what the common demominator is
x^2-4 * 3
x x-2
is it x-2? because it has an x and a 2??
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?
