Answer:
x = -
, x =

Explanation:
Given
x² - x -
= 0 ( add
to both sides )
x² - x =

Solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2( -
)x +
=
+

(x -
)² = 1 ( take the square root of both sides )
x -
= ± 1 ( add
to both sides )
x =
± 1
Thus
x =
- 1 = -

x =
+ 1 =
