    Answer:

    That can be re-written:

    x^2 + 5x -8 = 0

    We use the Quadratic Formula

    a=1

    b = 5

    c = -8

    x = [-b +- sq root (b^2 – 4ac) ] / 2a

    x = [-5 +- sq root (25 – – 32)] / 2

    x1 = [-5 + sq root (57)] / 2

    x1 = 1.27491722

    x2 = [-5 – sq root (57)] / 2

    x2 = -6.2749172176
