Find all the zeros of the polynomial 
, if two of its zeros are 
and 
.
We know that if 
is a zero of a polynomial then 
Since -√2 and √2 are zeros of 
Therefore 
and 
are factors of 
.
Now on dividing 
to find other zeros.
By applying division algorithm, we have:
= 
(
)
Hence, the zeros of the given polynomial are: 
12
