    (x - 2)

    Step-by-step explanation:

    Given the quadratic

    x² - 7x + 10

    To factor consider the factors of the constant term ( + 10) which sum to give the coefficient of the x - term ( - 7)

    The factors are - 5 and - 2 since

    - 5 * - 2 = + 10 and - 5 + ( - 2) = - 7, thus

    x² - 7x + 10 = (x - 5) (x - 2)
