OpenStudy (specek18):

@skullpatrol please help me....do you know this?

OpenStudy (skullpatrol):

Do you have any ideas?

OpenStudy (skullpatrol):

what is the definition of a "least common denominator" @specek18 ?

OpenStudy (specek18):

i know it's a super long process...

OpenStudy (specek18):

it is a number that will go into all

OpenStudy (arbyj):

i dont know this stuff im sorry,

OpenStudy (alesia/bailey):

umm, ive never learned this.

OpenStudy (skullpatrol):

what do you mean by " go into all " ?

OpenStudy (specek18):

like it will go into all the parts of the problem...idk i just need the answer:(

OpenStudy (skullpatrol):

do you now how to factor the denominators?

OpenStudy (specek18):

no..

OpenStudy (skullpatrol):

$$\Huge n^2 +4n+4 =(n+2)^2$$ right?

OpenStudy (specek18):

as the final or the factored?

OpenStudy (skullpatrol):

as a statement, do you understand it or not?

OpenStudy (specek18):

kind of...how do u get the answer from there?

OpenStudy (skullpatrol):

you must learn to factor this expression:$$\Huge n^2+7n+10$$

OpenStudy (specek18):

i know how:)

OpenStudy (specek18):

(n+n) (7+n)+10

OpenStudy (specek18):

i think...my test is timed is all...sorry.

OpenStudy (skullpatrol):

test?

OpenStudy (specek18):

yeah...

OpenStudy (specek18):

please help:"(

OpenStudy (skullpatrol):

but that would be cheating...

OpenStudy (specek18):

basically what this site is.

OpenStudy (skullpatrol):

factor this please $$\Huge n^2+7n+10$$

OpenStudy (specek18):

i don't got time for that. i gotta finish this thing.

OpenStudy (specek18):

and i already did earlier.

OpenStudy (skullpatrol):

it was not correct

OpenStudy (skullpatrol):

let me show you the pattern

OpenStudy (skullpatrol):

$$\Huge n^2+7n+10$$ $$\Huge n^2+(r+s)n+rs$$

OpenStudy (skullpatrol):

so rs = 10 and r + s = 7

OpenStudy (skullpatrol):

can you tell me what r and s are @specek18 ?

OpenStudy (skullpatrol):

$$\Huge n^2+7n+10 =(n+2)(n+5) $$
