Question

Factorise-
a^12 x^4 = a^4 x^12

Answer 1

Step-by-step explanation:

Using  a2−b2=(a+b)(a−b) at each step

Given:a12x4−a4x12

          =a4x4(a8−x8), factor out common factor a4x4

          =a4x4[(a4)2−(x4)2]

          =a4x4(a4+x4)(a4−x4)

          =a4x4(a4+x4)[(a2)2−(x2)2]

          =x4a4(a4+x4)(a2+x2)(a2−x2)

          =x4a4(a4+x

Answer 2

x^4 a^4(a^4+x)
