    (20+2) (20-2) = 20² - 2²

    20² - 2² = 396

    Step-by-step explanation:

    from the rule of the difference of two square which states thate

    (a + b) (a - b) = a² - b²

    therefore, 22 can also be written as (20 + 2),

    while 18 can be written as (20 - 2)

    therefore by the rule of the difference of two square the product of both expression will give

    (20+2) (20-2) = 20² - 2² = 400 - 4 = 396

    Step-by-step explanation:

    = (20 + 2) * (20 - 2)

    = 22 * 18

    = a^2 - b^2 = 396

    = (a + b) * (a - b) = 396

    From the above, a = 20 and b = 2.

    Therefore,

    (20^2) - (2^2) = 396.
