Answer:

See below ↓

Explanation:

Problem


  • (5x)/(x+7) + (7)/(x)

Work


  • (5x(x)+7(x+7))/(x(x+7))

  • (5x^(2) +7x+49)/(x(x+7))
  • The student's mistake was that instead of taking x(x + 7) as the LCM (Least Common Multiple), he took x + 7, which is not possible in this case

Solution


  • (5x^(2) +7x+49)/(x(x+7))
