Answer:

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

Step-by-step explanation:

Given :

To factorize,

x^4 - 6x^2y^2 + y^4

Solution :

x^4 - 6x^2y^2 + y^4

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

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

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

x^2(x^2-y^2) - y^2(x^2-y^2) - 4x^2y^2

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

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

By a² - b² = (a + b)(a - b)

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

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