x^2 - 8x + 15/x^2-25 times x + 5/x^2-9? Factor, Cross Cancel, Simplify!?!!?

Question

Anyone know the answer?

Answer 1

(x-3)(x-5) x+5
----------- ---------
(x-5)(x+5) (x-3)(x+3)

the 2 x-3 cancel out along with the 2 x+5 and 2 x-5

answer 1/x+3

Answer 2

( [ x^2 - 8x + 15 ] / [ x^2 - 25 ] ) ( ( x + 5 ) / [ x^2-9 ] )
factor
( [ (x-3) (x-5)] / [ (x+5) (x-5) ] ) ( ( x + 5) / [ (x+3) (x-3) ] )
(x-5) cancels in the left term
rewrite so there is one fraction and not a product of two fractions
