Question

Help Please :
Quotient Rule: x^6+x^3+3 / x+3

Answer 1

quotient rule:
havent had time to practive this in a while but:
(x^6+x^3+3) / (x+3)
((6x^5 + 3x^2 + 3)(x+3) - (1)(x^6 + x^3 + 3))/(x+3)^2

so...
(derivative of top*bottom - derivative of bottom*top)/(bottom)^2

Answer 2

found my first mistake in my problem...lets see if I can figure it out...thanks

Answer 3

I got that part...in order to do this first part of the equation its foiled right?

Answer 4

yes

Answer 5

u'v = (6x^5 + 3x^2 )(x+3)

Answer 6

oh yes. i got that wrong. sorry.

Answer 7

I'm confuse the way they told me to remember it is : Lo D HI - Hi D Lo divided by Lo ^2 ...i keep getting the wrong answer though

Answer 8

once i simplified I got 5x^6+18x^5+2x^3+9x^2 -3 / (x+3)^2 but it says its wrong

Answer 9

Atleast I got the first part correct :)

Answer 10

why wouldnt that negative be distributed though

Answer 11

so to simplify further i woul get 7x^6+18x^5+4x^3+9x^2+3 / (x+3)^2 ...yes?

Answer 12

= ( 5x^6 +18x^5 + 2x³ + 9x² - 3 )/ (x+3)²

Answer 13

Thats what I got as well but when I tried to submit it saidd it was wrong...that cant be simpliefied further even if you were to do the square cuz youd get x^2 +9x+9

Answer 14

let me double check
couldve made a typo when I submitted it

Answer 15

yup I double checked what i submitted and what i wrote down on my scrape paper ...the problems specified to simplify but it cant be simplified further...thats the only thing i can think of

Answer 16

Thanks for your help...i keep questioning myself on these quotient rule problems and as i quadruple checked my work i caught that I wrote down the equation wrong...so i did it correctly with the way i rewrote it but it wasn't what the question was...thanks so much though I appreciate it

Answer 17

Make sure the answer is:
= ( 5x^6 +18x^5 + 2x³ + 9x² - 3 )/ (x+3)²

Answer 18

we both got the same answer with how i wrote it but the denominator on the problem was supposed to be x^3+3....which changes the answer completely...I keep making stupid mistakes

Answer 19

I'm sorry I think your misinterpreting me ....the original problem was
x^6+x^3+3 / x^3 +3....when i worked it out I missed that is was x-cubed

Answer 20

With what we worked out the answer should be correct cuz we both got the same answer but with the denominator being cubed it changes the whole answer

Answer 21

Okie, so it's because your post is incorrect :(

Answer 22

yes when i worked out the problem I missed it...i just worked out another problem so hopefully i get it correct so I know that i understand it

Answer 23

i feel like a dope ...i'm sorry i feel horrible

Answer 24

YAAAAAAAAAAAAYYYYYYYYYYYYYYYYY ....i got it right !!!!! thanks so much !!!!!!
