Answer:

x = 8 ± 2i $\sqrt{2}$

Step-by-step explanation:

Given

x² - 16x + 60 = - 12 ( subtract 60 from both sides )

x² - 16x = - 72

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 8)x + 64 = - 72 + 64, thus

(x - 8)² = - 8 ( take the square root of both sides )

x - 8 = ± $\sqrt{-8}$ = ± 2i $\sqrt{2}$ ( add 8 to both sides )

x = 8 ± 2i $\sqrt{2}$
