Question

Which of the following is equal to the rational expression when x ≠ -4 or 16

Answer 1

Answer:

A

Step-by-step explanation:

(x^(2)-16)/((x-16)(x+4))=

[(x+4)(x-4)]/(x-16)(x+4)=

x-4/x-16

Answer 2

Answer:

$\dfrac{x - 4}{x - 16}$

Step-by-step explanation:

$\dfrac{x^2 - 16}{(x - 16)(x + 4)} =$

$= \dfrac{(x + 4)(x - 4)}{(x - 16)(x + 4)}$

$= \dfrac{x - 4}{x - 16}$
