Solve for x: (x – 4)^2 = 2?

Answer 1

Favorite Answer

(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!

:)

Answer 2

(x-4)² = 2

√(x-4)² = +- √2

x - 4 = +- √2

x = 4 +- √2...............ANSWER

Answer 3

(x – 4)^2 = 2

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

D = x - 4

(x - 4) ( x- 9 ) =

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

Answer 4

(x-4)^2=2

x-4=+or-squareroot(2)

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

Answer 5

take the square root of both sides.

x-4=(+/-)sqrt2

x=(+/-)sqrt2+4.
