2. Confirm that 1+V5 and 1 - V5 are the correct roots for x2 – 2x – 4 = 0.
hoa [83]

Answer:

see explanation

Step-by-step explanation:

Given

x² - 2x - 4 = 0 ( add 4 to both sides )

x² - 2x = 4

To solve use the method of completing the square

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

x² + 2(- 1)x + 1 = 4 + 1

(x - 1)² = 5 ( take the square root of both sides )

x - 1 = ± \sqrt{5} ( add 1 to both sides )

x = 1 ± \sqrt{5}, thus

x = 1 + \sqrt{5} or x = 1 - \sqrt{5}
