Answer 1

how would you solve this?

Answer 2

factor it out first which i did and got \[\frac{ n^{2}-6 }{ n ^{2}-2 }\] but i want to know how would i find the restrictions

Answer 3

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

when either of these equals zero, the denominator is zero

Answer 4

Ok so what do i do? im sorry im not very good in math.

Answer 5

When does a product equal 0?

a*b

Answer 6

Oh god im so dumb /.\ the answer was in front of me the whole time. Just add the 2 and you would have n^2=2 then square root it and you have √2 would that be right?

Answer 7

Set it equal to 0 first, but yeah

Answer 8

and do the same for (n^2-5) right?

Answer 9

yeah. and when you take the square root of 5, remember that you add the plus minus sign because:\[(-5)^2 = 25 = (5)^2\]
