1. "the graph has the same zeros" : so let a be the "triple" root of the cubic polynomial function.
2. So f(x)=

3. Don't forget that the expression might have a coefficient b as well, and still maintain the conditions:  

4. Now, f(0)=-5 so  




5. the function is 

 where a can be any real number except 0

Answer:
 (15c + 8)(a + b). 
Step-by-step explanation:
 15c·(a+b)+8·(b+a)
(a + b) is common to both parts:
= (15c + 8)(a + b).
 
        
             
        
        
        
EXPLANATION:
To get the solution of the simultaneous equation, using the elimination method:
We will have the following steps:
Step 1:
Write the two equations:

Step2: Subtract the two equations:

Step 3: Simplify the expression

Step 4: Substitute x=-2 into the formula:

Therefore, the answer is

Thus,
Option B is correct
