Answered on 23 Jun Tuition

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... ...more

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
