If x+y+z=6, xy+yz+zx=11. Find the value fo `x^(2)+y^(2)+z^(2)`.

If ( x +y+z ) = 9 and ( xy + yz + zx ) = 26 then find the value of x^(2) + y^(2) z^(2)

If x + y + z = 10, x ^(3) + y ^(3) + z ^(3) = 75 and xyz = 15, then find the value of x ^(2) + y ^(2) + z ^(2) - xy - yz - zx

If x = 6, y = 4 and z = 3, then find the value of x ^(2) + y ^(2) + z ^(2) - 2xy + 2 yz - 2 zx.

If x=997 , y=998 z=999 then the value of x^(2)+y^(2)+z^(2)-xy-yz-zx will be

If x+y+z=2, xy+yz+zx= 11, then the value of x^3 +y^3 +z^3 - 3xyz is: यदि x+y+z=2, है, xy+yz+zx= 11 है तो x^3 +y^3 +z^3 - 3xyz का मान होगाः

If (x+y+z)=6 and (xy+yz+zx)=11 , then the value of (x^(3)+y^(3)+z^(3)-3xyz) is :
