Question

Factorise: x 4 − (y + z)4

Answer 1

Answer:

X4-4y-4z

=4(x-y-z)

Thats the answer

Answer 2

Answer:

x 4 - ( y +z ) 4

=(x  2 )  2 −{(y+z)  2 } 2

 =(x  2 +(y+z)  2 )(x  2 −(y+z)  2 )

=(x  2 +(y+z)  2 )(x+y+z)(x−y−z)

=(x  2  +y  2 +z  2  +2yz)(x+y+z)(x−y−z)

=1×(x  2 +y  2  +z  2 +2yz)×(x+y+z)×(x−y−z)
