Question

x cubed over x squared - 4 divided by x cubed - 9x squared over x squared + 7x -18

Answer 1

could someone help me get started please

Answer 2

its difficult to parse the question; can you rewrite it into something more discernable please?

Answer 3

or use () paranthesis around stuff that is supposed to be grouped together? like perhaps:

(x cubed over x squared) - (4 divided by x cubed - 9x) squared over (x squared + 7x) -18

Answer 4

x cubed over x squared - 4 divided by x cubed - 9x squared over x squared + 7x- 18

Answer 5

x^3/x^2-4/x^3-9x^2/x^2+7x-18

Answer 6

Need to know where parentheses are.

Answer 7

no parentheses

Answer 8

that just leaves order of operations i guess :)

Answer 9

x - (4/x^3) - 9 +7x -18

Answer 10

@amistre64 yes

Answer 11

8x -27 -(4/x^3)

8x^4 -27x^3 -4
----------------
x^3

Answer 12

- (4/x^3) +8x -27

Answer 13

x squared divided by x cubed - 9x square
___________ _____________________
x squared - 4 x squared + 7x-18

Answer 14

sorry this is the question:
x cubed divided by x cubed - 9x squared
___________ ______________________
x squared - 4 x squared +7x - 18

Answer 15

\[\frac{\frac{x^3}{x^2-4}}{\frac{x^3 -9x^2}{x^2 +7x -18}} ???\]

Answer 16

that came out tiny ;)

Answer 17

thats it

Answer 18

factor everything so you know what to cancel out;

Also, take the bottom "fraction"; turn it over, spank it, and multiply it to the top "fraction"; like this:

xxx (x+9)(x-2)
--------- * ----------
(x-2)(x+2) xx (x-9)

Answer 19

Now cancel like terms top tp bottom

x(x+9)
----------
(x+2) (x-9)

Answer 20

thank you, I had it right, I really appreciate it.

Answer 21

youre welcome :) its alot easier to solve when you can "read" the problem ;)

Answer 22

are you ready for another one

Answer 23

I spose.... whatcha got?

Answer 24

m squared - n squared
--------------------
5m - n m = - 1/5 and n= 1/5

Answer 25

so you just fill in the variables with the values?

Answer 26

1/25 - 1/25 = 0

0/anything = 0

Answer 27

could someone please help me with factoring
