Urgent Help!!!

jhonyy9 (jhonyy9):

hi

OpenStudy (shaleiah):

\[(3n^5+13n^4+8n^3-42n^2-n+18)/(3n-2)\]

OpenStudy (shaleiah):

I need help with Division Polynomials

jhonyy9 (jhonyy9):

can i trying help you

jhonyy9 (jhonyy9):

(3n5+13n4+8n3−42n2−n+18)/(3n−2) ok. so long division will be accepted ?

OpenStudy (shaleiah):

yes

jhonyy9 (jhonyy9):

the 3n you need multiplie by what to get 3n^5

jhonyy9 (jhonyy9):

no ok, i will tel you this so by n^4 bc 3n*n^4 = 3n^5 yes ?

OpenStudy (shaleiah):

alright

jhonyy9 (jhonyy9):

sorry (3n5+13n4+8n3−42n2−n+18)/(3n−2) = n^4 3n^5 -2n^4 ------------ subtract second from the first 0 15n^4 +8n^3 so now you need multiplie the 3n by what to get 15n^4 ?

jhonyy9 (jhonyy9):

shaleiah please collaborate

jhonyy9 (jhonyy9):

15/3 = ?

OpenStudy (shaleiah):

5

jhonyy9 (jhonyy9):

yes n^4 ---- = ? n

OpenStudy (shaleiah):

2

jhonyy9 (jhonyy9):

n on exponent 4 divide by n = ?

jhonyy9 (jhonyy9):

you need getting n on what power ?

OpenStudy (shaleiah):

i'm not sure

jhonyy9 (jhonyy9):

n^4 --- = n^4 *n^(-1) = n^(4-1) = n^? n

OpenStudy (shaleiah):

3

jhonyy9 (jhonyy9):

4-1 yes so will be n^3 but above you get an 5 what mean that 3n*5n^3 = 15n^4

jhonyy9 (jhonyy9):

(3n5+13n4+8n3−42n2−n+18)/(3n−2) = n^4 + ? 3n^5 -2n^4 ------------ subtract second from the first 0 15n^4 +8n^3 so now you need multiplie the 3n by what to get 15n^4 ?

jhonyy9 (jhonyy9):

on place of ? what you need writing there ?

OpenStudy (shaleiah):

5n^3

OpenStudy (shaleiah):

@jhonyy9

jhonyy9 (jhonyy9):

(3n5+13n4+8n3−42n2−n+18)/(3n−2) = n^4 + 5n^3 3n^5 -2n^4 ------------ subtract second from the first 0 15n^4 +8n^3 so now you need multiplie the 3n by what to get 15n^4 ? 15n^4 -10n^3 ---------------- 0 18n^3 -42n^2 so now with what you need multiplie the 3n to get 18n^3 ?

OpenStudy (shaleiah):

12n

OpenStudy (shaleiah):

@jhonyy9

jhonyy9 (jhonyy9):

why or how ? 18/3 = 12 ?

OpenStudy (shaleiah):

Ah, 6

jhonyy9 (jhonyy9):

(3n5+13n4+8n3−42n2−n+18)/(3n−2) = n^4 + 5n^3 +6n^2 3n^5 -2n^4 ------------ subtract second from the first 0 15n^4 +8n^3 so now you need multiplie the 3n by what to get 15n^4 ? 15n^4 -10n^3 ---------------- 0 18n^3 -42n^2 so now with what you need multiplie the 3n to get 18n^3 ? 18n^3 -12n^2 ---------------- 0 30n^2 -n and now you need multiplie the 3n to get 30n^2 by ?
