I need help understanding this and some answers quick

Hoochie [10]

Answer:

(x - 8)² = 14

Step-by-step explanation:

Given

x² - 16x + 26 = - 24 ( subtract 26 from both sides )

x² - 16x = - 50

To complete the square

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

x² + 2(- 8)x + 64 = - 50 + 64

(x - 8)² = 14
