" (ii) "1+y^(3)+8z^(3)-6yz

If x+y+z=6 and xy+yz +zx =11 then what is the vlaue of x^(3) +y^(3)+z^(3) -3xyz ?

If (x + y + z) = 16 and xy + yz + zx = 75, then x ^(3) + y ^(3) + z ^(3) - 3xyz is

If x+y+z=8 and xy+yz+zx=20 find the value of x^(3)+y^(3)+z^(3)-3xyz

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

Factorize the following expressions 1+y^3+8z^3-6yz

Simplify: 2-3z^(2)+5yz+7y^(2)-8+z^(2)-6yz-9y^(2)+1-2z^(2)-2yz-y^(2)

In each polynomial, given below, separate the like terms : y^(2)z^(3), xy^(2)z^(3), -5x^(2)yz, -4y^(2)z^(3), -8xz^(3)y^(2), 3x^(2)yz and 2z^(3)y^(2)
