[" 1.If "x+2y+3z=0" and "],[x^(3)+4y^(3)+9z^(3)=18xyz" ; evaluate : "],[((x+2y)^(2))/(xy)+((2y+3z)^(2))/(yz)+((3z+x)^(2))/(zx)]

If x + 2y + 3z = 0 and x^(3) + 4y^(3) + 9z^(3)= 18 xyz , evaluate: ((x+2y)^(2))/(xy) + ((2y + 3z)^(2))/(yz) + ((3z+ x)^(2))/(zx)

If x^(3)+y^(3)+z^(3)=3xyz and x+y+z=0, find the value of ((x+y)^(2))/(xy)=((y+z)^(2))/(yz) +((z+x)^(2))/(zx)

If x+2y+3z=0 and x^3+4y^3+9z^3=18xyz then evaluate (x+2y)^2/(xy)+(2y+3z)^2/(yz)+(3z+x)^2/(zx)

If x^(3)+y^(3)+z^(3)=3xyz and x+y+z=0 , then the value of ((x+y)^(2))/(xy)+((y+z)^(2))/(yz)+((z+x)^(2))/(zx) is

If x^(3) + y^(3) + z^(3) = 3xyz and x + y + z = 0 , find the value of : ((x+y)^(2))/(xy) + ((y+z)^(2))/(yz) + ((z+x)^(2))/(zx)

Evaluate : (2x-y+3z)(4x^(2)+y^(2)+9z^(2)+2xy+3yz-6xz)

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

Simplify : (x- 2y + 3z ) ( x^(2) + 4y^(2) + 9z^(2) + 2xy + 6yz - 3xz)
