Answer:
x = 2, -1
Step-by-step explanation:
x² - x + 1 = 3
- 3 -3
x² - x - 2 = 0
(x -2)(x + 1)

The distance travelled by east bound car is 60 km.
<u>Explanation:</u>
Distance travelled by North bound plane = 63 km
Distance travelled by east bound plane = 87 km
Distance travelled by east bound plane = ?
The trajectory of the plane would form a triangle.
In a right angle triangle:
(hypotenuse)² = (base)² + (height)²
(87)² = (b)² + (63)²
7569 = b² + 3969
b² = 3600
b = 60 km
Therefore, distance travelled by east bound car is 60 km.
