What are the answer choice options
Her argument is true because you can tell 492,111 and 409,867 are closer 1,025,680 snd 45,760 is alot farther away. Glad to help
Factor the numerator and denominator...
(n^4-5n^2-6n^2+30)/(n^4-2n^2-5n^2+10)
[n^2(n^2-5)-6(n^2-5)]/[n^2(n^2-2)-5(n^2-2)]
[(n^2-5)(n^2-6)]/[(n^2-5)(n^2-2)] notice the (n^2-5)s cancel out
(n^2-6)/(n^2-2)
We could further factor this because each is a difference of squares to:
[(n+√6)(n-√6)]/[(n+√2)(n-√2)
First combine like terms.
9x + 2x = 11x.
That's all you have to do!
Your final answer is 11x - 8!
Have a nice day :)
