Question

Factorise each of the following: x⁴ – 16y⁴​

Answer 1

Answer:

the answer is below

Step-by-step explanation:

=x⁴– 16y⁴

=(x²)² – (4y²)²

=(x²+4y²)(x²–4y²)

=(x²+4y²)(x–2y)(X+2y)

Answer 2

Answer:

(x²+4y²)(x²-4y²)

Step-by-step explanation:

x⁴-16y⁴

(x²)²-(4y²)² ( Identity- (a+b)(a-b)=a²-b² )

(x²+4y²)(x²-4y²)
