3 will cancel into 9:
1. + = = 3n
:
2. +
Factor the 2nd denominator and you can see that you can add the numerators:
+ =
The (x+8)'s will cancel, leaving:
:
Same rules apply here:
3. + =
However, the denominator can be factored (the difference of squares)
You can see he (a-2)'s will cancel leaving us with:
