What should be added to xy+yz+zx to get -xy-yz-zx

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

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

Factorize- xy-yz-zx+z^2

Obtain the product of : xy, yz, zx

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

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

Prove that |[yz-x^2,zx-y^2,xy-z^2],[zx-y^2,xy-z^2,yz-x^2],[xy-z^2,yz-x^2,zx-y^2]| is divisible by (x+y+z), and hence find the quotient.

Add: 7xy + 5yz - 3zx, 4yz + 9zx - 4y, - 3xz + 5x - 2xy

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