    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?
