Factor this quadratic equation: x^2-2x-1

Part A:
The sequence of transformations :
- Reflection over the y-axis.
- Vertical translation 3 units down.
A ( - 4, 4 ) Reflection → ( 4, 4 ) Translation→ A` ( 4, 1 )
B ( - 2 , 2 ) → ( 2 , 2 ) → B` ( 2, - 1 )
C ( - 2 , - 1 ) → ( 2, - 1 ) → C` ( 2, - 4 )
D (  - 4 , 1 ) → ( 4 , 1 ) → D` ( 4, - 2 )
Part B :
Yes. Quadrilaterals ABCD and A`B`C`D` are congruent.
Reflection and translation are transformations that preserves the shape of an object.
