6 0

Answer:

The answer to your question is the second choice

Step-by-step explanation:

                        4x/ (x - 7)  -  (x +7) / x

- Find the greatest common factor from x and (x - 7)

                 GCF = x(x - 7)

- Substract the terms

                     [4x(x) - (x + 7)(x - 7)] / x(x - 7)

- Simplify

                     [ 4x² - x² + 49] / x(x - 7)

                     [ 3x² + 49] / x(x - 7)

- Result

                      3x² + 49  /  x(x - 7)
