Answer 1

(X^2+5)/(x+5)(x-5)
(X+1)(x-5)/(x+5)(x-5)
(X-1)(x+5)/(x+5)(x-5)

Answer 2

(x²+5)/(25 -x²) = (x²+5)/ (-(x² -25)) =  -(x²+5)/(x²-25) =-(x²+5)/(x-5)(x+5)   =  -(x²+5)/(x² -25) ;
(x+1)/(x+5) = (x+1)(x-5)/(x-5)(x+5)  =         (x²-4x+5)/(x² -25) ;
(x-1)/(x-5) =(x-1)(x+5)/(x-5)(x+5) =            (x² +4x -5)/(x² -25) .
