Question

If x+y+z=0 then prove that 1/x^2+y^2-z^2 +1/y^2+z^2-x^2 +1/z^2+x^2-y^2 =0​

Answer 1

let's x=0

y=0

z=0

So,

${x}^{2} = 0$

${y}^{2} = 0$

${z}^{2} = 0$

Answer 2

Answer:

let's x = 0

y = 0

z = 0

so ,

x² = 0

y ² = 0

z² = 0

hope it helps you

please thanks my answer I also give you
