Simplify x^4 - 3x^3 over x^2 - 9? TEN POINTS BEST ANSWER!!! :)

Simplify:
x^4 - 3x^3
-----------
x^2 - 9

Simplify:
14 - 7x
---------
x - 2

Simplify:
x^2 - 16
----------
x^2 - 8x + 16

Simplify:
x^2 - x - 20
--------------
x^2 + 8x + 16

Simplify:
x^2 + x - 2
---------
x^2 - 1

x^4 - 3x^3
----------- =
x^2 - 9

x^3 (x - 3)
-------------- =
(x + 3) (x - 3)

x^3 / (x + 3)

You get the idea, now do they other ones yourself.

Moderators really should delete questions like this where people just have others do their homework and don't ask conceptual questions

simplify should be easy O.o it not like solving it
