    (x - 7) (x - 3)

    Step-by-step explanation:

    Given

    x² - 10x + 21

    Consider the factors of the constant term ( + 21) which sum to give the coefficient of the x - term ( - 10)

    The factors are - 7 and - 3, since

    - 7 * - 3 = + 21 and - 7 - 3 = - 10, thus

    x² - 10x + 21 = (x - 7) (x - 3)
