Question

factorise the sum- x⁴-y⁴​

Answer 1

Answer:

here is your answer hope it helps....

Step-by-step explanation:

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

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

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

Answer 2

Step-by-step explanation:

x⁴-y⁴

(x²)²-(y²)² {a²-b²=(a+b)(a-b)}

(x²+y²) (x²-y²)

(x²+y²) (x+y)(x-y)
