Solve the value of x using undoing, rewriting, and looking inside strategies.

x = 0, x = 4

Step-by-step explanation:

Given

(x - 2)² - 3 = 1 ( add 3 to both sides )

(x - 2)² = 4 ( take the square root of both sides )

x - 2 = ± = ± 2 ( add 2 to both sides )

x = 2 ± 2

Thus

x = 2 - 2 = 0

x = 2 + 2 = 4
