Question

Simplify the rational expression. State any restrictions on the variable. n^4-11n^2+30/n^4-7n^2+10

Answer 1

\[\frac{n^4-11n^2+30}{n^4-7n^2+10}=\frac{(n^2-5)(n^2-6)}{(n^2-5)(n^2-2)}=\frac{n^2-6}{n^2-2}\]

Answer 2

I hope this helps...

Answer 3

thank you, but which are the restrictions and how did you find them?

Answer 4

well they are similar to a quadratic equation aren't they

Answer 5

would it be n=/+-(squared)5, n=/(squared)2?

Answer 6

oh ok u want to find the values of n, i thought u just said simplify

Answer 7

it's both

Answer 8

\[n= \pm \sqrt{6} \space and \space n= \pm 2\]

Answer 9

it's not an option for my homework, it should have a 5 and 2

Answer 10

it is impossible to have a 5 and 2 u'll have to have sqrt 5 and sqrt 2

Answer 11

6

Answer 12

i am pretty sure there is an error in the answers provided

Answer 13

yeah I chose the answer that squared 5 and 2

Answer 14

it should be 6 and 2, the 5s are canceled out

Answer 15

as i showed u above

Answer 16

there is no 5

Answer 17

\[n= \pm \sqrt{6} \space and \space n= \pm \sqrt{2} \space or \space n^2= 6 \space or \space n^2= 2\]

Answer 18

i think that i know what the problem is

Answer 19

all of the answers have a =/ sign instead of an = sign

Answer 20

\[\neq\]

Answer 21

well is sqrt n a rational number or not?

Answer 22

if it is not a rational number then u restrict it to not equal

Answer 23

otherwise its equal

Answer 24

i think this is clear to u now

Answer 25

yes it does, thanks for clarifying =)

Answer 26

all the best, so why is it TooMuch hehehe?

Answer 27

because I have way too much to do all the time, anyway I'll give you best response

Answer 28

thanks ur welcome...

Answer 29

no problem, hopefully we can work together some time again :)
