    George Washington died on December 14th, 1799

    Numerical with the arrangement: month - day - year

    12 - 14 - 1799

    Step-by-step explanation:

    In the question, we are told that: the month in which he died and the day of the month on which he died are consecutive even integers whose product is 168.

    Therefore,

    If one positive even integer = Month he died is represented by x

    The second consecutive even integer = Day he died = x + 2

    Their product =

    x (x + 2) = 168

    x² + 2x = 168

    x² + 2x - 168 = 0

    We factorise

    x² + 14x - 12x - 168 = 0

    (x² + 14x) - (12x - 168) = 0

    x (x + 14) - 12 (x + 14) = 0

    (x - 12) (x + 14) = 0

    x - 12 = 0, x = 12

    x + 14 = 0, x = - 14

    Our answer cannot be a negative interger, hence x = 12

    So the first positive even integer = 12

    The second positive even integer = x+2 = 12 + 2 = 14

    Therefore, the month he died = n = 12th month = December

    The day he died = n + 2 = 14 = 14th day.

    Hence, George Washington died on December 14th, 1799

    Numerical with the arrangement: month - day - year

    12 - 14 - 1799
