Question

x^4 - ( x-z ) ^ 4 solve

Answer 1

x^4-(x-z)^4
x^4-{(x-z)^2}^2
x^4-{x^2+z^2-2xz}^2}
x^4-{x^4+z^4+4x^2z^2+2x^2z^2-4xz^3-4x^3z}
-(z^4+6x^2z^2-4xz^3-4x^3z)

Answer 2

Answer:

-(z^4+6x^2z^2-4xz^3-4x^3z)

Step-by-step explanation:

x^4-(x-z)^4

x^4-{(x-z)^2}^2

x^4-{x^2+z^2-2xz}^2}

x^4-{x^4+z^4+4x^2z^2+2x^2z^2-4xz^3-4x^3z}

-(z^4+6x^2z^2-4xz^3-4x^3z)
