Your answer would be A
He had 6 dogs 
4x6d=24
        
             
        
        
        
First bring them to common denominator.
        
             
        
        
        
Let's actually find the roots, using the quadratic formula:
<span>p(x)=x^2+x+3 gives us a=1, b=1 and c=3.
                 -1 plus or minus sqrt(1^2-4(1)(3))
Then x = -----------------------------------------------          
                                           2
The discriminant here is negative, so the roots x will be complex:
              -1 plus or minus sqrt(-11)      -1 plus or minus i*sqrt(11)
       x = ---------------------------------- = -------------------------------------
                          2                                                 2
These are irrational roots; they cannot be expressed as the ratios of integers.</span>
