Question

I need help with simplifying this equation :P i totally dont remember the steps :P

its in an attachment

Answer 1

whats the equation

Answer 2

its not letting me uplaod hold on a sec :)

Answer 3

here :)

Answer 4

can u see it ok?

Answer 5

yep

Answer 6

remember that when you change a division into a multiplication you have to flip the number ?

Answer 7

Yep. so u would do that to the the second equation?

Answer 8

reciprocal or something?

Answer 9

yeah, on the second term

so it would look like

(3x+12)/(4x-18 * (x-3)/(x+4)

Answer 10

alright.

Answer 11

when you factor out the common factors from the left rational expression, what do you get?

Answer 12

Arggghhh so hard to solve in that typed format :P hold on

Answer 13

what does 3x+12 factor into?

Answer 14

are you asking me what it is ?

Answer 15

nvm the "are you ~" part

Answer 16

No of course not i am trying to talk to my mother and you and other people all at the same time therefore its hard to concentrate :P so hold on lol sowee about not answering so quickly :P

Answer 17

Hmmmm i think the answer is A maybe C do u agree? or did it not attach that part :P

Answer 18

3x+12 factors into 3(x+4), so it cancels with the denominator of the right side of the rational expression

Answer 19

right.

Answer 20

these are my choices :)

Answer 21

4x-18 does factor into 2(2x-9), but you have no term on the numerator that cancels with this , so it is a waste

Answer 22

so it is C then...

Answer 23

the uhhuh looks right

Answer 24

lol so u like my labels... ^^

Answer 25

oops

Answer 26

lol and okie dokie :P totally off on that one

Answer 27

it's the yep, sorry I didn't look at it carefully

Answer 28

woo hoo! thats the one i thought it might be!!! :)

Answer 29

most rational expressions work exactly the same way,
so as long as you can factor polynomials, all you have to
do is to see which one divides out and cancel.

Answer 30

hmmm so the answer to this one i will attach them would be A?

Answer 31

and alright i see! :)

Answer 32

hoot would be the answer

Answer 33

because \[x^2-16 = (x+4)(x-4)\]

Answer 34

only (x-4) divides out

Answer 35

Ahhhh alright i can see why i was wong. ^^ oh ok like 1 or two more.. :) So then on this one:

Answer 36

it would be

Answer 37

It would be YA right? :P im a little lost on this concept :p

Answer 38

this one you cannot cancel anything, so you do long division

Answer 39

are you comfortable with it?

Answer 40

Not rly :P never been very good at it :P

Answer 41

give me a couple of min to show you how it works,
I cannot type it so I will upload a file
