    b^2 - 6b - 55

    Step-by-step explanation:

    (b + 5) (b - 11)

    Use FOIL

    First

    Outside

    Inside

    Last

    F: b * b = b^2

    O: b * - 11 = - 11b

    I: 5 * b = 5b

    L: 5 * - 11 = - 55

    b^2 - 11b + 5b - 55

    Combine like terms

    -11b + 5b = - 6b

    b^2 - 6b - 55
