Solve x2 + 4x − 4 = 0
hoa [83]

Answer:

third option

Step-by-step explanation:

Given

x² + 4x - 4 = 0 ( add 4 to both sides )

x² + 4x = 4

Using the method of completing the square

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

x² + 2(2)x + 4 = 4 + 4, that is

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

x + 2 = ± \sqrt{8} = ± 2\sqrt{2} ( subtract 2 from both sides )

x = - 2 ± 2\sqrt{2}
