It is Given that
x² +y² +z² = xy - yz - zx
⇒ x² +y² +z² - xy - yz - zx = 0 ...........(i)
Since,
x³ + y³ +z³ - 3xyz = (x + y+ z)( x² +y² +z² - xy - yz - zx)
then
x³ + y³ +z³ - 3xyz = (x + y+ z) x 0 .... (from i )
x³ + y³ +z³ - 3xyz = 0
x³ + y³ +z³ = 3xyz
Hence, if x² +y² +z² = xy - yz - zx then x³ + y³ +z³ = 3xyz
