    D

    Step-by-step explanation:

    Given

    x² + 2x + 13 = - 8

    To be able to factor the quadratic and go on to solve we require the equation to be in standard form, that is

    ax² + bx + c = 0, thus

    Add 8 to both sides ← first step, gives

    x² + 2x + 21 = 0 ← in standard form
