Answer:


(x^2+y^2+xy)(x^2+y^2-xy)

Explanation:

Rewrite the middle term.


x^4+2x^2y^2-x^2y^2+y^4

Rerrange terms.


x^4+2x^2y^2+y^4-x^2y^2

Factor first three terms by perfect square rule.


(x^2+y^2)^2-x^2y^2

Rewrite
x^2y^2 as
(xy)^2.


(x^2+y^2)^2-(xy)^2

Since both terms are perfect squares, factor using the difference of squares formula,
a^2-b^2=(a+b)(a-b) where
a=x^2+y^2 and
b=xy.


(x^2+y^2+xy)(x^2+y^2-(xy))

Remove parentheses.


(x^2+y^2+xy)(x^2+y^2-xy)
