Answer 1

Answer:

Step-by-step explanation:

If you're dividing x^2 - 16 by  x - 4, please enclose the x - 4 inside parentheses.  Thanks.

 x^2 - 16        (x + 4)(x - 4)

--------------- = -------------------  = (x - 4)  ONLY for x ≠ -4, because

    x + 4              x + 4               division by zero is not defined.
