Answer 2

\[\frac{ n }{ 2-n } - \frac{ 2 }{ n-2 }\]

Answer 3

Is that your question

Answer 4

Yes

Answer 5

it would really be helpful if you used the equation tool below
fortunately @iambatman is good a mind reading

Answer 6

just another superpower i guess

Answer 7

I can't is not working on my side

Answer 8

\[\huge \frac{ a }{ b }-\frac{ c }{ d } = \frac{ ad-bc }{ bd }\] you could use this property

Answer 9

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

Answer 10

just to get it out there I like that username Batman

Answer 11

Just start simplifying now, and thanks haha :)

Answer 12

okay ur welcome

Answer 13

so it will be A

Answer 15

because I have to cancel out the ( 2 -n) and (n-2) and that what I got

Answer 16

\[\frac{ n(n-2)-2(2-n) }{ (2-n)(n-2) } \implies \frac{ n^2-2n-4+2n }{ (2-n)(n-2) }\] right?

Answer 17

\[\frac{ n^2-4 }{ (2-n)(n-2) } \implies \frac{ (n-2)(n+2) }{ (2-n)(n-2) } \implies \frac{ n+2}{ 2-n }\]

Answer 18

okay cool I have 3 more question it hard multitasking

Answer 19
