Answer:
6x^2-5x+5
Step-by-step explanation:
Answer:
x = -
, x = 
Step-by-step 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 =
