what ever remainder you have left you have to keep it divided by x + 2

I know how to do it, it's just I don't know if I put it over x + 2 > \[\frac{ x + 2 }{ 72 }\]

What do you have for your long division?

x+2 remains in the denominator and it should be 60

I know that; it's just I need help with where the 72 goes and @Australopithecus it's not 60

when you subtract; it's like you're distributing  into the second equation http://assets.openstudy.com/updates/attachments/50875f3ae4b058e80cf64652.sam.13510501095142.png

Like when you are subtracting 11x^2  12x  (11x^2 + 22x)

you are are trying to cancel and get rid of the 11x^2

It should be 34x  8  (34x + 68)

.Sam.Best ResponseYou've already chosen the best response.1
You should be careful there, its actually 8(68)

Are you getting confused??? @.Sam.

don't memorize the facts, just remember that it is top minus the bottom, you look back the previous steps, all you do is to subtract the top one with the bottom one, the steps that I gave you is computer generated, its completely true.

Firejay5Best ResponseYou've already chosen the best response.0
you have to apply the negative (34x + 68) to all number s in parentheses
 one year ago

AustralopithecusBest ResponseYou've already chosen the best response.0
a remainder is just part of the equation that you cannot divide, so it is left with the denominator so in your case 60/(x+2)

.Sam.Best ResponseYou've already chosen the best response.1
The actual answer is 60, why are you ignoring it? Take a look at the picture below.

I'm basing my 60/(x+2) on the wolfram alpha simplification
 one year ago

Firejay5Best ResponseYou've already chosen the best response.0
It's not 34x  68 it's (34x + 68) the minus/negative in front of the parentheses goes with everything in it
