Answer 7

but u just did... lol

Answer 8

well, it was an explanation

Answer 9

\[\Large\bf\sf \frac{x}{(x+3)} + \frac{x+2}{(x+5)}\]

Answer 10

yes

Answer 11

but technically there are no parenthesis around the bottom two

Answer 12

I just started re-doing it, let me show you what I did

Answer 13

I multiplied x+3(x+5) and got x^2+8x+15

Answer 14

Technically, yes :) But we'll need to add parenth any time we do multipication.

Answer 15

write it as (x+3)(x+5) :O

Answer 16

ok looks good.

Answer 17

that's what i did so far, is it right

Answer 18

the last 2 steps are:
Write it as a single fraction and combine like-terms in the numerator.
Factor the numerator in your last step.

Answer 19

The draw tool isn't working properly today :( I can't see the picture.

Answer 20

ok hold on

Answer 21

there

Answer 22

In the very first step, is the bottom left supposed to be x+3?

Answer 23

woops,yes

Answer 24

mm ok then your work looks good so far!

Answer 25

No pictures silly!! XD

Answer 26

Err no drawings i mean :3

Answer 27

I had to put it so I could take a screenshot, so I could show u the screenshot.

Answer 28

Oh i see

Answer 29

ok, so I'm not really sure how to combine the numerators

Answer 30

I'm going to put a screenshot of the work I sent to my teacher, so you can tell me what I did wrong, ok

Answer 31

\[\Large\bf\sf \frac{stuff}{x^2+8x+15}+\frac{junk}{x^2+8x+15}\quad=\quad \frac{stuff+junk}{x^2+8x+15}\]They have the same denominator, so we can just combine them like this.

Answer 32

but is it multiplying?

Answer 33

No, just addition.

Answer 34

ok

Answer 35

did u see my previous work?^ up there

Answer 36

ok, its x^4+10x+6

Answer 37

the only problem that I made in my previous work was I wrote x^4+10x+10

Answer 38

We shouldn't end up with any x^4.

See how we have a bunch of x and x^2 ?
Adding those will give us x and x^2 's.
