If x > 7, which of the following is equal to (x^2 - 6x + 9)/(x^2 - 9) ?
Choose the correct choice from the following answers
A) (x + 4)/(4(x - 4)) B) (x - 4)/(x + 4) C) (x - 3)/(x + 3) D) (x + 4)/(x - 4) E) (x - 8)/(x - 4)
(x^2 - 6x + 9)/(x^2 - 9)   = (x - 3)(x - 3) / (x + 3)(x - 3)   =(x - 3)/(x + 3)   C. (x - 3)/(x + 3)
<result>C</result>
