Homework Help: Find the integer zeros for equation of degree 8 ?

    Find the integer zeros for equation of degree 8 ???

    Hi I am trying to find the integer zeros of the equation:


    I know that I need some substitution to make the degree goes down.
    for example Let U=(some thing on x), and V=(some thing on y)

    I think the solution depend on Pell's equations or Diophantine equations

    I tried to put U=x and V=y^2 but did not know to do after that

    Please help
