    x = (i sqrt (7)) / 4 - 3/4 or x = - (i sqrt (7)) / 4 - 3/4

    Step-by-step explanation:

    Solve for x:

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

    Bring x - 1 - 2/x together using the common denominator x:

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

    Multiply both sides by x:

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

    Expand out terms of the right hand side:

    x^2 - x - 2 = 3 x^2 + 2 x

    Subtract 3 x^2 + 2 x from both sides:

    -2 x^2 - 3 x - 2 = 0

    Divide both sides by - 2:

    x^2 + (3 x) / 2 + 1 = 0

    Subtract 1 from both sides:

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

    Add 9/16 to both sides:

    x^2 + (3 x) / 2 + 9/16 = - 7/16

    Write the left hand side as a square:

    (x + 3/4) ^2 = - 7/16

    Take the square root of both sides:

    x + 3/4 = (i sqrt (7)) / 4 or x + 3/4 = - (i sqrt (7)) / 4

    Subtract 3/4 from both sides:

    x = (i sqrt (7)) / 4 - 3/4 or x + 3/4 = - (i sqrt (7)) / 4

    Subtract 3/4 from both sides:

    Answer: x = (i sqrt (7)) / 4 - 3/4 or x = - (i sqrt (7)) / 4 - 3/4
