lukranit [14]2 years ago
7 0

Answer:

Step-by-step explanation:

2) a(a + b) + b(a - b) - 2ab / a² - b²

= a² + ab + ab - b² - 2ab / a² - b²

= a² - b² / a² - b²

= 1

3) [x - 1/(x - 1)(x - 2)] + [x - 2/(x -2)(x - 3)]

= (1 / x - 2) + (1 / x - 3)

= x - 3 + x - 2 / (x - 2)(x - 3)

= 2x - 5 / x² - 5x + 6
