Question

using factor theorem , show that (x-y) is a factor of x(y^2-z^2) + y (z^2-x^2) + z ( y^2-x^2) )​

Answer 1

Step-by-step explanation:

I'll not write the answer. I'll give you a hint. in the equation put x=y. Then you'll get it zero.

And according factor theorem if f(c)=0 then x-c is a factor of the equation.
