You can put this solution on YOUR website! -Its degree is seven. 
   -It has only integer coefficients.
 
  ,  ,  ,  ,  ,  ,  are integers -Its zero include
  as only rational ones. 
   -Its zero include
  (multiplicity 1) and -2root(2)(multiplicity 1). 
   
   since complex roots and  square root  always come in pairs, we will have
  and  too since we need seven roots, we use
  three times and, using zero product theorem we have:
 
   when all multiplied, we get
 
  which is your polynomial
