If `x+y+z=5` and `xy+yz+zx=3` then least and largest value of x are:

Let x,y,z in R be such that x+y+z=5 and xy+zy+zx=3 the largest possible value of 'x' is

if x+y+z=1 and xy+yz+zx=1/3 then find x:y:z

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=3 and xy+yz+zx = -18, then what is the value of x^3+y^3+z^3-3xyz = ? यदि x+y+z=3 और xy+yz+zx = -18 है, तो x^3+y^3+z^3-3xyz =?
