Factorize ` 1+x+y-z+xy-yz-zx-xyz`

Factorize- xy-yz-zx+z^2

What should be added to 2xy+3yz+4zx+5xyz to get x+y+z+2xy+3yz+zx-xyz ?

If xneynez and |[x,x^3,x^4-1],[y,y^3,y^4-1],[z,z^3,z^4-1]|=0 , then prove that : xyz(xy+yz+zx)=x+y+z

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, xy+yz+zx=-11 है ,तो x^3+y^3+z^3-3xyz का मान ज्ञात करें |

If x+y+z=2, xy+yz+zx =-11 and xyz =-12, then what is the value of sqrt(x^3 + y^3 +z^3-2) ?

Subtract 3xy + 5yz- 7zx from 5xy - 2yz -2zx + 10xyz

If 'x+y+z and xy+yz+zx and xyz is given find the value of x^(^^)3+y^(^^)3+z^(^^)3

Prove that , tan^(-1)""x+ tan^(-1) ""y+tan^(-1)""z= tan ^(-1)""(x+y+z-xyz)/(1-xy-yz-zx)
