x = 1 ± 3 $\sqrt{2}$

Step-by-step explanation:

Given

(x - 1)² - 18 = 0 ( add 18 to both sides )

(x - 1)² = 18 ( take the square root of both sides )

x - 1 = ± $\sqrt{18}$ = ± $\sqrt{9(2)}$ = ± 3 $\sqrt{2}$ ( add 1 to both sides )

x = 1 ± 3 $\sqrt{2}$ , thus the exact solutions are

x = 1 - 3 $\sqrt{2}$

x = 1 + 3 $\sqrt{2}$
