Answer:

Step-by-step explanation:
We are given 

Let's assume it can be factored as 

now, we can multiply right side
and then we can compare it 


now, we can compare coefficients



now, we can find all possible factors of 48
and then we can assume possible prime factors of 48





Since, we have to find the largest value of n 
So, we will get consider larger value of r because of 5r
and because n is negative of 5r+s
so, we will both n and r as negative 
So, we can assume 
r=-48 and s=-1
so, we get
