Answer:
Step-by-step explanation:
x⁴-(x-z)⁴=(x²+(x-z)²)(x²-(x-z)²)
=(2x²+2xz+z²)(x+x-z)(x-x+z)
=(2x²+2xz+z²)(2x-z)z
=z(2x-z)(2x²+2xz+z²)

Answer:
→ z(2x-z)(2x²+2xz+z²)
Step-by-step explanation:
→ x⁴-(x-z)⁴
=[x²+(x-z)²] [x²-(x-z)²]
= (2x²+2xz+z²) (x+x-z) (x-x+z)
= (2x²+2xz+z²) (2x-z)z
= z(2x-z)(2x²+2xz+z²)
