Question

Simplify the rational expression. State any restrictions on the variable.

Answer 1

\[\frac{ n^4 - 11n^2 + 30 }{ n^4 - 7n^2 + 10 }\]

Answer 2

Factor both polynomials

Answer 3

@Mertsj (n - 5)(n - 6)/ (n - 5)(n - 2) ?

Answer 4

@Mertsj ???? please help

Answer 5

\[\frac{(n^2-5)(n^2-6)}{(n^2-5)(n^2-2)}\]

Answer 6

@Mertsj then what ?

Answer 7

Tell the restrictions on the variable and cancel the n^2-5

Answer 8

@Mertsj 5 and - 2 ?

Answer 9

i mean 2

Answer 10

\[n^2-5 \neq0\]

Answer 11

n^2-5 cannot be 0 so n^2 cannot be 5 and n cannot be sqrt 5 or - sqrt 5

Answer 12

Similarly n^2-2 cannot be 0 so n^2 cannot be 2 and n cannot be sqrt 2 or - sqrt 2
