Well, good luck on your test tonight, but your first question is missing something!
1) = ?
2) Factor the numerator.
Cancel the common factor (r+1) and you are left with:

r^2-5r-6/r+1=?
((r-6)(r+1))/(r+1)=?
(r-6)=?
If the question mark was zero, then the answer would be 6!
x^2-10x+35=?
x^2-10x=-35 --minus 35
(x-5)^2=-10 --take x minus half of the negative 10
(x-5)=i(10)^(1/2) --sqaure root the whole equation
or
(x-5)=-i(10)^(1/2) --sqaure root the whole equation
The answer is:
x=5+(10^(1/2)
or
x=5-(10^(1/2)
....(these are the answer if ? was equal to zero)
