Answer:
1. 

2. 

3. 

Step-by-step explanation:
1. The given polynomial is

We need to factor the second part to get:

We factor y-5 to obtain:

2. We have 

We again factor -1 from the second part to get:

We now factor x-y to get:


3. We have 

We factor negative 1 from the first part to get

We now factor b-3 to get:

We now simplify to get:

Answer:
C. 31 kilometers north of its starting location
Step-by-step explanation:
<em>Please see attached a rough sketch of the situation for your reference</em>.
Step one:
Displacement North= 57km
Displacement South= 26km
Required 
The  final displacement
The current position is attained by subtracting 26km from 57km
=57-26= 31km
Therefore the current position is
C. 31 kilometers north of its starting location
