Question

factories using identities: x^4-(x-z) ^4​

Answer 1

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 2

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)
