x4 + x2 y2 + y4 = (x4 + 2x2 y2 + y4) - x2 y2
= (x2 + y2)2 – (xy)2
= [(x2 + y2) + xy] *[(x2 + y2) - xy]
=> x4 + x2 y2 + y4 = (x2 + xy + y2) *(x2 - xy + y2)
= (x2 + y2)2 – (xy)2
= [(x2 + y2) + xy] *[(x2 + y2) - xy]
=> x4 + x2 y2 + y4 = (x2 + xy + y2) *(x2 - xy + y2)

I am not confirm about your question but is this correct or not.
The last answer is (x^2+y^2+xy)(x^2+y^2-xy)
<Hope it helps>
