Answer 2

To get the answer to this problem you first factor out the common term 2

(n+3)/(2(n-3) ) * (n+3)/(3n-9)

then factor out the common term 3

(n+3)/(2 (n-3) ) * (n+3)/(3 (n-3) )

then simplify

( (n+3)(n+3)/(2 (n-3)*3(n-3) )

Use product rule : x^a x^b= x^a+b

( (n+3)^2/(2 (n-3)*3(n-3) )

simplify 2 (n-3) * 3(n-3) to 6(n-3)(n-3)

( (n+3)^2/(6 (n-3)(n-3) )

use product rule again : x^a x^b=x^a+b

so you get the answer : ( (n+3)^2)/(6 (n-3)^2 )

so the orrect answer to this problem is answer choice (C)
