Question

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

Answer 1

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

I have it simplified, I just need help finding restrictions ;)

\(\Large\frac {(n^2-6)(n^2-5)} {n^2-2)(n^2-5)}\) = \(\Large\frac {n^2-6} {n^2-2}\)

Answer 2

Look at the original expression. Specifically at the denominator when it is factored.

Answer 3

When does it equal 0?

Answer 4

One second ;)

Answer 5

Thanks! :D

Answer 6

what 4 values of n were you able to find?
