Answer 22

the second is not 1
can you write your calculation here

Answer 23

\[\frac{ x^2 - 4 }{ x-2 }\]
If you fill x with 2, then it would be :
0/0

That's mean you need to factorize it :
\[\frac{ (x + 2)(x-2) }{ x-2 }\]
you can divide x-2 by x-2, the quotient would be:
x + 2
Fill x with 2 :
2 + 2 = 4
