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 =

Answer:
Option B). 10 cm
Step-by-step explanation:
Distance between center and the focus of an ellipse is given by the formula,
c² = a² - b²
where, a = length of the major axis
b = length of the minor axis
and c = distance between focus and center
If c = 6 cm, b = 8 cm,
6² = a² - 8²
a² = 6² + 8²
a² = 36 + 64
a² = 100
a = 10 cm
Therefore, length of the major axis is 10 cm.
Option (B) is the answer.
I believe the answer the answer is 5.1 b
