Question

factorise x⁴-y⁴ hope to answer fast​

Answer 1

Answer:

x4-y4

(x2) 2-*(y2) 2

(x2+y2) (x2-y2)

(x2+y2) (x-y) (x+y)

Answer 2

(x² + y²)(x + y)(x - y)

Step-by-step explanation:

QUESTION :-

Factorise x⁴ - y⁴

__________________

SOLUTION :-

We will use only one formula here,

a² - b² = (a + b)(a - b)*

Now,

x⁴ - y⁴ can be written as

(x²)² - (y²)²

=> (x² + y²)(x² - y²)

[by the above formula as a = x² & b = y²]

=> (x² + y²)(x + y)(x - y)

[using the formula written above, a = x, b = y]

hence,

The factorisation is (x² + y²)(x + y)(x - y).
