    Step-by-step explanation:

    Well ... if you remember that a^2 - b^2 = (a+b). (a-b), you solve the numerator of the question ...

    Rewriting that, You'll find (3+x). (3-x) / x^2

    When you divide it by (3+x) / x^2 you'll see a product just like that:

    (3+x). (3-x) / x^2. x^3 / (3+x)

    Right now it's simple because you have to write in a simplest form:

    x. (3-x) = 3x - x^2

    You can write this on your notebook to see these division of binomials and writing in a simplest form.
