Answer 1

can someone tell me steps of how to do this???

Answer 2

Factor it out!

Answer 3

first let n^2 be lets say a

Answer 4

okay that really helped i need steps im new at this so im lost

Answer 5

ok we make n a

Answer 6

(a^2-10a+24)/(a^2-9a+18) now u can do the rest.....or

Answer 7

Answer 11

factorize the numerator and denominator
(a-6)(a-4)/(a-3)(a-6)
(a-4)/(a-3)
but a=n^2
(n^2-4)/(n^2-3)

Answer 12

i dont know what i did but i screwed up thats all i know

Answer 13

dont u understand it?

Answer 14

@arhin no

Answer 15

@arhin, she also needs to know the restriction that n^2 \( \ne \) 6, and why.
