1. ## Multiply fractions

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:

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

If that's not it, let me know.

Now factor the numerator in your first fraction.

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

Can you finish?

3. ok well that makes sense!! thanks

3(x+2)
x

Correct??
