16x⁴ - y⁴ Please Factorise This Question​

Answer 1

Answer:

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

Step-by-step explanation:

by using the formula:

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

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

(4x^2-y2)(4x^2+y^2)

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

as you can see (4x^2-y2) this can be more simplified as we are using the formula x^2 - y^2 = (x-y)(x+y)

(4x^2-y2) is this 4 is the square of 2 so [(2x)^2 - (y)^2] = (2x - y)(2x + y)

we can't simplify this (4x^2 + y^2) because this is not like the formula x^2 - y^2 = (x-y)(x+y)

hope this is helpful
