I have answered ur question
Ответ:
A
Step-by-step explanation:
Given
x² - 8x = 3
To complete the square
add (half the coefficient of the x- term)² to both sides
x² + 2(- 4)x + 16 = 3 + 16
(x - 4)² = 19 ( take the square root of both sides )
x - 4 = ±
( add 4 to both sides )
x = 4 ±
Solution set is (4 -
, 4 + 
)
