Answer:
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.
