1.
((c + 8)(c - 8))/((c - 8)(c + 3))_,_

(c + 8)/(c + 3)_,_

2.
(n^(2) + 4n - 12)/(n^(2) + 2n - 8)_,_

(n^(2) + 6n - 2n - 12)/(n^(2) + 4n - 2n - 8)_,_

(n(n) + n(6) - 2(n) - 2(6))/(n(n) + n(4) - 2(n) - 2(4))_,_

(n(n + 6) - 2(n + 6))/(n(n + 4) - 2(n + 4))_,_

((n - 2)(n + 6))/((n - 2)(n + 4))_,_

(n + 6)/(n + 4)_,_

3.
(42x^(2)y^(3))/(28x^(3)y)_,_

(3y^(2))/(2x)_,_

4.
(m^(2) - 3m - 10)/(m - 5)_,_

(m^(2) - 5m + 2m - 10)/(m - 5)_,_

(m(m) - m(5) + 2(m) - 2(5))/(m - 5)_,_

(m(m - 5) + 2(m - 5))/(m - 5)_,_

((m + 2)(m - 5))/(m - 5)_,_

m + 2_,_
