Question

Factorise a¹²x⁴-a⁴x¹²​

Answer 1

Answer:

a^4*x^4*(a^4+x^4)*(a^2+x^2)*(a+x)*(a-x)

Step-by-step explanation:

a^12*x^4-a^4*x^12​=

a^4*x^4*(a^8-x^8)=

a^4*x^4*(a^4+x^4)*(a^4-x^4)=

a^4*x^4*(a^4+x^4)*(a^2+x^2)*(a^2-x^2)=

a^4*x^4*(a^4+x^4)*(a^2+x^2)*(a+x)*(a-x)

Answer 2

a4x4(a4+x4)a2+x2(a+x)(a-x)
