Question

factorise (x-z)^4-x^4​

Answer 1

HERE IS YOUR ANSWER

x4-(x-z)4

x4-(x2-2xz+z2)2

x4 - (x4-2x3z+x2z2-2x3z+4x2z2-2xz3+x2z2-2xz3+z4)

Combine like terms

x4 - (x4-4x3z+6x2z2-4xz3+z4)

4x3z-6x2z2+4xz3-z4

Answer 2

Answer:

(x-z)⁴-x⁴

=((x-z)²)²-(x²)²

=((x-z)²+x²)((x-z)²-x²)

=(x²-2xz+z²+x²)(x-z+x)(x-z-x)

=(2x²-2xz+z²)(2x-z)(-z)
