Divide by 4
(x - 2)^2 = 48
Take the Square Root
x - 2 = +/- SQRT(48)
Simplify
x - 2 = +/- 4 SQRT(3)
Solve
x = 2 +/- 4 SQRT (3)

4(x-2)^2=192
divide both sides by 4
(x-2)^2 = 48
take a square root of both sides
x-2 = + or - sqrt(48)
add 2 for both sides
x = + or - sqrt(48) + 2
x = + or - 4 sqrt 3 + 2

(x - 2)² = 48
(x - 2) = 屉48
(x - 2) = ± 4â3
x = 2 ± 4â3 is an acceptable form for answer.
(tidier than changing to decimals)

4(x-2)^2=192
(x-2)^2=192 /4
(x-2)^2=48=3*16
x-2=+ or - 4sqrt(3)
x=(+ or - 4sqrt(3)) +2
