    (x-4)(x-4) = 2

    FOIL and solve

    Or for an easier way, just square root both sides to get

    x - 4 = /- sqrt(2)

    x = 4 +/- sqrt(2)

    Either way works!

    (x-4)² = 2

    √(x-4)² = +- √2

    x - 4 = +- √2

    x = 4 +- √2...............ANSWER

    (x – 4)^2 = 2

    (x -- 4)^2 x 8 = 2 x 8

    D = x - 4

    (x - 4) ( x- 9 ) =

    8====D ~~~<> {{}}

    (x-4)^2=2

    x-4=+or-squareroot(2)

    X=4+squareroot(2) or x=4-squareroot(2)

    take the square root of both sides.

    x-4=(+/-)sqrt2

    x=(+/-)sqrt2+4.
