Is that
f(x) = x^2 + x - 2
----------
x + 1
Just making sure

- Hayhayz

yes it is

can i help u dont know if i can but i could sure try

- Hayhayz

yea

- FortyTheRapper

Go for it Maurtice, ill help if you get stuck

- Hayhayz

http://prntscr.com/9e51cg these are the answer choices btw

- MaurticeWilliams

the only thing about that problem that confuses me is the weird looking a thing other wise the uh i think u have to substitute the f for a number and times it by x

- tootzrll

okay, in the chat it looked easier but i think i know what to do

- MaurticeWilliams

u can substitute f for any number

- FortyTheRapper

You can find it with synthetic division

- MaurticeWilliams

synthetic division never heard of it

- tootzrll

ummm... i got lost.... sorry

- FortyTheRapper

Alright, so let's take a simple division.... 100/10
So you would take the 10 and put it on the outside, Then you would make the "Doghouse" symbol and put the 100 under that
Does that make sense?

- MaurticeWilliams

so that A looking thing is a doghouse symbol

- MaurticeWilliams

yeah now it does

- Hayhayz

|dw:1450118011802:dw| is that right??

- FortyTheRapper

Almost
The 1 on the very left should be a different number, it should be negative
Because on the bottom you had x+1 right? So you would have to find our what x value would give make x+1=0

- MaurticeWilliams

it should have been a negative im learnu=ing from this

- MaurticeWilliams

learning

- FortyTheRapper

Right, a -1

- Hayhayz

|dw:1450118201130:dw|

- FortyTheRapper

Correct!

- Hayhayz

then what do i do?

- FortyTheRapper

Alright, so in the original problem, what was the highest exponent in the numerator?

- MaurticeWilliams

wrong file!

- MaurticeWilliams

don't pay attention to that

- Hayhayz

2

- FortyTheRapper

Right, so the first number will be 1x, because you found that to be 1 after division
and you're highest powers always go down by 1 when finding obliques using division

- FortyTheRapper

The second thing in the numerator of the original problem was an x, which is also x^1
So if you lower that, that would equal x^0, right? Which is 1. That make sense so far?

- MaurticeWilliams

hey can u help me with something

- Hayhayz

yes it does

- MaurticeWilliams

do u know what a linear function is

- MaurticeWilliams

rise slope all that stuff

- FortyTheRapper

Cool, so the second number you found in your answer is 0, so (x^0) times 0 is 0
Which means so far we have x + 0, with that -2 on the end
The -2 is the last number in your answer, which means it was the remainder. You always scratch off those, since we don't bother with those

- MaurticeWilliams

i know a little about it but always mess something up

- Hayhayz

Maurtice if you have a question could you post it instead of on my question haha

- FortyTheRapper

After scratching that off we get x+0, also known as?

- Hayhayz

wait so the answer is just x

- FortyTheRapper

Exactly!

- Hayhayz

ahhh okay thank you so much!!

- FortyTheRapper

Anytime!

- Hayhayz

could you help me in another one?

- FortyTheRapper

Sure!
