If X + Y + Z equal to 9 and xy + Y Z plus ZX equal to 23 then x cube +?
Verified Answer
If X + Y + Z equal to 9 and xy + Y Z plus ZX equal to 23 then x cube +...
-> (x^3 + y^3 + z^3 - 3xyz) 
= (x + y + z) (x^2 + y^2 + z^2 - xy - yz - zx)
= (x + y + z) [(x + y + z)2 - 3(xy + yz + zx)]
= 9 x (81 - 3 x 23)
= (9 x 12)
= 108
