The fundamental theorem of algebra states that a polynomial with degree n has at most n solutions. The "at most" depends on the fact that the solutions might not all be real number.
In fact, if you use complex number, then a polynomial with degree n has exactly n roots.
So, in particular, a third-degree polynomial can have at most 3 roots.
In fact, in general, if the polynomial  has solutions
 has solutions  , then you can factor it as
, then you can factor it as

So, a third-degree polynomial can't have 4 (or more) solutions, because otherwise you could write it as

But this is a fourth-degree polynomial.
 
        
             
        
        
        
The answer would be 11/14
        
                    
             
        
        
        
 
as the following pic you can see the answer.
#diameter is 8 so radius is 4
 
        
             
        
        
        
Answer:
It will be 0.5 repeating so 0.555 because the 5 is repeating 
 
        
                    
             
        
        
        

We need to find the number of pies baked in years 1 and 2.
There were 148 pies baked in year 1. 
There were  pies baked in year 2.
 pies baked in year 2. 
Rearrange the terms so the variable is first.
