    Bab Limit

    Lim (√(2x -1) - √(3x + 5))
    x→∞

    = Lim (√(2x -1) - √(3x + 5)) . (√(2x -1) + √(3x + 5))/(√(2x -1) + √(3x + 5))
       x→∞

    = Lim ((2x - 1) - (3x + 5) / (√(2x -1) + √(3x + 5))
       x→∞

    = Lim (-x - 6)/(√(2x -1) + √(3x + 5))
       x→∞

    = Lim (-x/x - 6/x) / (√((2x -1)/x²) + √((3x + 5)/x²))
       x→∞

    = (-1 - 0) / (√0 + √0)
    = -1/0
    = -∞
