    Answer:

    (x + 4)(x + 5)

    Step-by-step explanation:

    Given

    x² + 9x + 20

    Consider the factors of the constant term (+ 20) which sum to give the coefficient of the x- term (+ 9)

    The factors are + 4 and + 5, since

    4 × 5 = 20 and 5 + 4 = 9, hence

    x² + 9x + 20 = (x + 4)(x + 5)
