Answer 2

Answer:

• C. x < -1 or 1 < x < 9/5

Step-by-step explanation:

• 2/(x - 1) > 7/(x + 1)
• [7(x - 1) - 2(x + 1)]/(x - 1)(x + 1) < 0
• (7x - 7 - 2x - 2) / (x - 1)(x + 1) < 0
• (5x - 9) / (x - 1)(x + 1) < 0

Zero's in the ascending order:

• x = -1, x = 1, x = 9/5

Negative intervals:

• x < -1, 1 < x < 9/5

Correct choice is C
