    2/(x + 3) - 3/(x - 2)
    = (2 . (x - 2) - 3 (x + 3))/((x + 3) . (x - 2))
    = (2x - 4 - 3x - 9)/(x² - 2x + 3x - 6)
    = (-x - 13)/(x² + x - 6)
    = (x + 13)/(6 - x - x²)
  • 2/(x + 3) - 3/(x - 2)
    = 2(x - 2)/(x + 3)(x - 2) - 3(x + 3)/(x + 3)(x - 2)
    = 2(x - 2) - 3(x + 3)/(x + 3)(x - 2)
    = 2x - 4 - 3x - 9/(x + 3)(x - 2)
    = -x - 13/(x + 3)(x -2)

    Semoga membantu!!!
