Answer 1

Answer:

(x+y)(y+z)(z+x)

Step-by-step explanation:

Taking first Numerator

N=(x²-y²)³+(y²-z²)³+(z²-x²)³

Here (x²-y²)+(y²-z²)+(z²-x²)=0

so N=(x²-y²)³+(y²-z²)³+(z²-x²)³=3(x²-y²)(y²-z²)(z²-x²)----------------(1)

similarly  Denominator

D=(y-z)³+(z-x)³+(x-y)³=3(y-z)(z-x)(x-y)

So fraction=N/D=3(x²-y²)(y²-z²)(z²-x²)/3(y-z)(z-x)(x-y)

=(x+y)(y+z)(z+x)
