Step-by-step explanation:
Given that the mean salary for a new teacher in your town is $48,000
You believe it is higher for new teachers in a neighboring town.
So to prove or disprove your claim you have to show statistical evidence.
For that hypothesis testing is necessary.
You must conduct a hypothesis test for comparing the mean of salary of new teacher with neighbouring places
The hypotheses wouldbe

where mu is the average for neighbouring states.
You have to extract common factor 3a^2
=> 3a^2 (5 x^2 + 4x + 3)
If you need help to know where each term inside the parenthesis come from, this is hoy you do it:
15a^2x^2
------------- = 5x^2
3a^2
12a^2x
----------- = 4x
3a^2
9a^2
-------- = 3
3a^2
Answer: 3a^2 (5x^2 + 4x + 3)
