Question

factorise x^4-(x-z)^4​

Answer 1

Step-by-step explanation:

x²+xz-4x-4z^4

x×x×x×z×2×2×x×2×2×z×2×2

Answer 2

Answer:

x  ^4 −(x−z)  ^4

=(x  ^2  )  ^2  −{(x−z)  ^2 }  ^2

=(x  ^2 +(x−z)  ^2  )(x  ^2 −(x−z)  ^2  )  ^2

=(x  ^2 +x  ^2 −2xz+z  ^2  )(x+x−z)(x−x+z)

=(2x  ^2  −2xz+^2  )(2x−z)(z)
