Answer 1

is this
3 4
--- - ---- - 9x
x x^2

Answer 2

(3/x - 4/x^2 - 9x)*x^2 = 3x - 4 -9x^3

Answer 3

If my post is correct then take suzi20's answer over x^2 and you will have your answer

Answer 4

no 4
-------
x^2 - 9x

Answer 5

oh.. then you find the common denominator

x = x
and x^2 - 9x = x(x - 9)

so your common denominator is x(x - 9)

(x-9)3 4
------- - -------
x(x-9) x(x-9)

3x - 27 4
------ - --------
x(x - 9) x(x-9)

3x - 31
-------
x^2 - 9x

Answer 6

3(x^2-9x) 4x
-------- - --------
x(x^2-9x) x(x^2-9x)

Answer 7

oh i'm late hahhaa
