    x = 3/8 + / - i (√5) / 8.

    Step-by-step explanation:

    I can't see any list by this is the solution of the equation:

    x^2 - 3/4x = - 1/4

    x^2 - 3/4 x + 1/4 = 0

    Multiply by 4 to remove the fractions:

    4x^2 - 3x + 1 = 0

    x = [ - (-3) + / - sqrt (3) ^2 - 4*4*1) ] / 8

    x = 3/8 + / -√ (-5) / 8

    x = 3/8 + / - √5 i / 8
