    The answer to this question is determined through the used of the equation,

    (-b + / - sqrt (b² - 4ac)) / 2a

    where a, b, and c are the numerical coefficients of the terms in the quadratic equation in order. Substituting the known values,

    x = (-16 + / sqrt (16² - 4 (34) (2)) / 2 (2)

    Simplifying,

    x = (-16 + / - sqrt (-4)) / 4

    The answer would be,

    x = - 4 + / - i

    The answer is letter D.
