hi everyone pls answer this question ... fast ... pls
Factorise : x⁴-y⁴​

Answer 1

Answer:

x4-y4

(x2)2-*(y2)2

(x2+y2)(x2-y2)

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

Mark me as brainiest

Answer 2

Answer: x4-y4

           [(x²)²-(y²)²]

           (x²+y²)(x²-y²)

          =  (x+y) (x+y)

Step-by-step explanation: Some important formulas:

(a+b)³ = a³+b³+3ab(a+b)

(a-b)³ = a³-b³-3ab(a-b)

a³+b³ = (a+b)(a²+b²-ab)
